How Do I Design Apps for Hotels and Guests?

When a guest arrives at a hotel after a long journey, do they really want to queue at reception for twenty minutes just to get their room key? After working on hotel apps for properties ranging from small boutique hotels to large chains with hundreds of rooms, I've learned that the answer shapes everything about how we design these applications... and the difference between a helpful app and one that gets deleted after checkout often comes down to understanding what guests actually want versus what hotels think they want to provide.

Hotel apps succeed when they solve real guest problems rather than just digitising a brochure

The hospitality industry has been slower to adopt mobile technology than sectors like retail or banking, partly because hotels serve such diverse guest needs. A business traveller checking in at 11pm wants something completely different from a family arriving for a week's holiday, yet both need to use the same app. This creates interesting design challenges that require careful thought about user journeys and feature prioritisation.

Understanding What Hotel Guests Actually Need From Mobile Apps

Look, the temptation when designing hotel apps is to pack in every possible feature... room service menus, spa bookings, local tourist information, weather updates, and on it goes. But here's what actually matters to guests based on usage data from apps we've built: they want to check in without queuing, they want their room key on their phone, they want to contact staff quickly when something needs fixing, and they want to see their bill before checkout.

Everything else is secondary.

We built an app for a 200-room hotel that initially wanted fifteen different features. After testing with real guests, 89% of all app interactions fell into just four categories: check-in, room access, housekeeping requests, and bill queries. The restaurant booking feature they'd insisted was critical? Used by fewer than 4% of guests who mostly just walked to the restaurant anyway. This mirrors the importance of focusing on core features rather than overwhelming users with too many options from the start.

Guest behaviour patterns change depending on the property type and trip purpose. Business hotels see heavy app usage between 6am and 9am (checking out) and after 8pm (checking in). Resort hotels get steadier usage throughout the day with peaks around meal times and activity bookings. Weekend leisure hotels see Friday evening and Sunday morning spikes. Understanding these patterns helped us design features that align with what modern travellers expect from their mobile experience.

• Pre-arrival information and early check-in requests
• Digital room keys that work offline
• Direct messaging with hotel staff
• Clear information about included services and paid extras
• Simple checkout process with bill breakdown
• Post-stay receipt access for expense claims

Room Booking Systems That Work Across Different Property Types

The booking functionality needs to handle wildly different scenarios depending on what you're building for. A city centre hotel might have twelve room types with dynamic pricing that changes every few hours based on demand. A small guesthouse might have five rooms with fixed seasonal rates. A resort could have rooms, suites, villas, and different meal plan options that affect pricing.

We connected a hotel app to their property management system that was running software from 2009. The API documentation was non-existent, so we spent three weeks reverse-engineering how their booking system actually worked. The lesson there was to always budget extra development time for legacy system integration... hotel technology infrastructure often lags years behind other industries. This is one of those hidden costs that can significantly impact your project timeline, similar to other development budget considerations that need careful planning.

Always show the total price including taxes and fees before guests enter payment details. Hidden charges revealed at the final step cause 34% of booking abandonments in our testing.

Real-time availability sync is non-negotiable. If your app shows a room as available when it's actually booked, you've created a terrible guest experience and a headache for reception staff. We poll the property management system every thirty seconds for availability changes, with immediate updates when a booking is made through the app itself. The server costs an extra £40 per month but prevents double bookings that could cost hundreds in compensation and damage to reputation.

Digital Check-In and Keyless Entry Implementation

Digital check-in sounds straightforward until you dig into the details. Guests need to confirm their arrival time, verify their identity, provide payment details for incidentals, review the terms and conditions, and potentially select room preferences or upgrades. That's a lot of information to collect on a mobile screen without making the process feel like filling out a tax return.

The best approach we've found is to split check-in into two stages. The first happens 24-48 hours before arrival when guests have time and aren't distracted by travel. This captures the bulk of required information. The second stage when they arrive is just identity verification and room assignment, taking under a minute.

Keyless entry technology varies significantly between different lock manufacturers. Some use Bluetooth Low Energy, others use NFC, and a few still rely on generating time-limited codes. We've worked with most major systems including Salto, Assa Abloy, and dormakaba. Each has different SDK requirements, battery consumption profiles, and reliability characteristics. For properties considering expanding beyond mobile, smartwatch integration can provide an even more seamless keyless entry experience.

1. Bluetooth locks provide the best user experience when they work, allowing doors to unlock as guests approach
2. NFC requires guests to tap their phone but is more reliable in buildings with thick walls
3. Generated codes work on any phone but require guests to manually enter numbers

The reality is that you need a backup plan for when digital keys fail... and they will fail sometimes. Flat phone batteries, Bluetooth connection issues, guests with older devices. We always implement a fallback that lets reception instantly generate a physical key card or temporary code through their system.

In-Stay Services and Guest Communication Features

Once guests are checked in, the app becomes their main touchpoint with hotel services. We've found that simple messaging works far better than elaborate service catalogs. A guest who needs extra towels doesn't want to navigate through three menu levels... they want to send a quick message and get a response.

The fastest way to damage your app's reputation is slow response times to guest messages

That means the staff-side tools need to be rock solid. Housekeeping, maintenance, and reception all need to receive requests instantly with clear priority flagging. A maintenance issue in a room needs immediate attention. A request for restaurant recommendations can wait until staff have a free moment.

Push notifications require careful calibration. Too many and guests disable them or delete the app. Too few and time-sensitive information doesn't reach them. We typically enable notifications for: room ready alerts, maintenance completion updates, replies to guest messages, and pre-checkout reminders. Marketing messages and upsell offers should be opt-in and sent sparingly. Building a proper communication strategy before launch is crucial, which is why establishing guest contact channels early in the development process pays dividends.

Service Request Prioritisation

Housekeeping requests for missing items get marked as routine (respond within 30 minutes). Maintenance issues like broken air conditioning or plumbing problems get flagged as urgent (respond within 10 minutes). Safety concerns like broken locks or electrical issues get marked as critical (immediate response with management notification).

Guest Communication Best Practices

Response time expectations differ by request type, but guests generally expect acknowledgment within five to ten minutes even if the actual service takes longer. A message saying "We've received your request and someone will bring extra pillows within 15 minutes" prevents guests from calling reception or submitting duplicate requests.

Payment Processing and Security for Hotel Apps

Hotel payment flows are more complicated than typical e-commerce because you're often taking a deposit before arrival, potentially authorising additional amounts for incidentals, processing various charges during the stay, and settling the final bill at checkout. Each stage has different security and compliance requirements, similar to the stringent standards required for mobile banking applications where security and user experience must work in harmony.

We handle payment card details through tokenisation, which means the app never stores actual card numbers. When a guest enters their card details, they're encrypted and sent directly to the payment processor (we typically use Stripe or Adyen for hotel projects) which returns a token. That token can be used to charge the card but is useless if stolen.

PCI DSS compliance is mandatory for any app handling payment cards. The requirements are extensive, covering everything from encryption standards to how long you can store transaction data. Most hotel apps reduce their compliance burden by using hosted payment pages where guests enter card details on screens controlled by the payment processor rather than the app itself.

Pre-authorisation holds need careful handling because they can cause confusion for guests. When you pre-authorise £200 for incidentals, that amount shows as unavailable in the guest's bank account even though you haven't actually charged it. Clear communication about holds, when they'll be released, and the final charged amount prevents complaint calls and negative reviews.

The checkout process should show an itemised bill that guests can review before final payment. Room charges, minibar items, restaurant bills, spa treatments... everything clearly listed with dates and amounts. We add a dispute option that flags items for reception staff to review before processing payment, which resolves billing questions before they become complaints. For business travellers especially, having detailed receipt functionality similar to comprehensive expense tracking solutions can significantly improve the user experience.

Building Apps That Work for Both Chain Hotels and Independent Properties

Chain hotels and independent properties have vastly different technical requirements and budgets. A chain might need the app to work across fifty properties in different countries with centralised reporting and brand consistency. An independent hotel needs something that works well for their specific property without paying for features they'll never use.

The architecture decision that works best in our experience is building a modular system where core features (booking, check-in, messaging) form the foundation and additional capabilities can be enabled per property. A budget hotel might only need basic booking and check-in. A luxury resort might want spa bookings, activity reservations, concierge services, and restaurant management.

Independent hotels typically have tighter budgets than chains but often move faster on decisions and implementation. Budget for £25k-45k for a solid independent hotel app versus £80k-150k for a multi-property chain solution.

White labelling lets you maintain one codebase while presenting different brands. The app looks and feels unique to each hotel group but shares the underlying technology. This dramatically reduces development and maintenance costs compared to building separate apps for each brand. When expanding internationally, it's essential to understand the additional complexities and costs that come with supporting multiple markets and currencies.

Offline Functionality and Connection Reliability

Hotel wifi is notoriously unreliable, and mobile signal inside buildings can be patchy. If your app requires constant internet connection, guests will struggle to use it exactly when they need it most... walking through corridors to their room with a digital key that won't unlock the door because there's no signal.

We build offline-first functionality for critical features. The digital room key credentials download to the phone when the guest completes check-in and work without internet connection. Bluetooth communication with the door lock happens locally. Only when the door successfully unlocks does the app need to sync that event back to the server, and if there's no connection it queues the data until signal returns.

Guest information like room number, check-in and check-out dates, and basic hotel details get cached locally. Service menus and contact information download in the background when connection is available. This means guests can browse the room service menu or find the hotel phone number even in a complete dead zone.

The tricky balance is security versus offline capability. You want digital keys to work without internet but you also need the ability to instantly revoke access if a guest checks out early or reports their phone stolen. We handle this by having keys expire after a set period (usually 24 hours) and requiring periodic connection to renew them. For extended stays, keys auto-renew each day when the phone has signal.

Connection Failure Handling

When the app detects no connection, we show a small indicator but don't block functionality that works offline. Error messages explain clearly what requires internet and when... "Booking a spa treatment needs an internet connection. Please connect to wifi or try again when you have signal."

Staff-Side Tools and Backend Systems

Guest-facing features get all the attention but the staff side makes or breaks operational efficiency. We've seen hotels abandon perfectly good apps because the admin tools were clunky and staff found it easier to just use their existing systems. When making decisions about feature priorities and staff training, it's helpful to look at industry data and adoption statistics to understand what works for similar properties.

Staff will bypass your app if it makes their job harder rather than easier

Reception staff need a dashboard that shows all pending check-ins, current occupancy, and maintenance issues at a glance. Clicking through multiple screens to find information doesn't work when there's a queue of guests waiting. We use a single-page design with live updates and quick action buttons for common tasks.

Housekeeping staff need a mobile-friendly interface they can use on tablets or phones as they work through rooms. The system should show which rooms are checked out and ready for cleaning, which are occupied but need servicing, and which have specific guest requests. Status updates (cleaning started, cleaning complete, maintenance issue found) happen with single taps.

Management needs reporting on app adoption rates, feature usage, guest satisfaction scores, and revenue generated through app bookings. But reports are only valuable if people actually look at them. We send daily summary emails with key metrics and weekly detailed reports, rather than expecting managers to log into another system to pull data. Converting app users into loyal customers requires understanding how to nurture relationships through strategic communication both during and after their stay.

Integration Requirements

Hotels run on property management systems that handle everything from reservations to billing to housekeeping schedules. Your app needs to integrate with these systems (common ones include Opera, Protel, and Mews) rather than creating duplicate data entry. We typically build two-way sync: bookings and guest data flow from the PMS to the app, while guest requests and preferences flow back to the PMS.

Conclusion

Designing apps for hotels means solving real operational problems rather than just creating a digital version of hotel services. The apps that succeed focus ruthlessly on the handful of features that genuinely improve the guest experience... faster check-in, reliable room access, and responsive communication with staff. Everything else is secondary.

The technical challenges around offline functionality, payment security, and legacy system integration require careful planning and realistic timelines. Hotels that rush development and launch with buggy apps damage their reputation far more than hotels with no app at all. Better to build a small set of features that work perfectly than a comprehensive feature list that frustrates guests and staff alike.

Building for hotels means understanding that every property is different, even within the same chain. Flexible architecture and modular feature sets let you adapt to specific needs without rebuilding from scratch each time. The goal is an app that makes both guests and staff say "this actually makes things easier" rather than "I'll just do it the old way."
