Wondering what makes a smart hotel “smart?” Although ChatGPT can’t change linens or comfort an angry guest (yet), hoteliers are leveraging technology in many facets of front-of-house and back-of-house operations. In short, a smart hotel enhances the guest experience with technology and utilizes technology to make operations more efficient. As innovation continues to rapidly improve hospitality-specific technology, hoteliers find more and more use cases for technology at their properties. And in today’s market conditions, technology is especially compelling because it can help you save money, stretch staff bandwidth, automate repetitive tasks, and better serve guests. Plus, guests are becoming more tech-savvy, as we can see from the rise in popularity of contactless payments and a shift toward contactless options in many industries.

In this article, we’ll explain the key benefits and features of smart hotels, then we’ll dive into some real-life examples of smart hotel activations from brands like Marriott and Hyatt. By the end of this article, you’ll have some ideas and inspiration to bring smart hotel technology to your property.

Benefits of Smart Hotels

Leveraging technology at your hotel can unlock two main benefits: an enhanced guest experience and improved operational efficiency. On the guest experience side, technology enables guests to enjoy more personalized services and preferences, since technology can solicit, store, and deliver customizations like communication preferences, room preferences, preferred language, and more. In addition, technology can deliver a more seamless check-in and checkout experience. Mobile check-in or physical hardware like kiosks can empower guests to complete check-in on their own, bypassing the line at the front desk. And technology can also give guests the tools to customize their room settings, like temperature and lighting, plus access amenities like in-room entertainment or room service menus.

But the benefits aren’t limited to guests; employees, managers, and owners can realize efficiencies when implementing technology that streamlines hotel operations. One of the most exciting benefits of technology is automation: rather than replacing employees, technology can shift manual tasks off of their plates and free up time to spend on more impactful tasks. Tasks like sending templated emails, requesting guest reviews, and sending invoices can be easily automated, potentially taking hours of repetitive work off your staffs’ to-do lists. Another way technology can benefit your bottomline is through energy management; technology like building management systems can reduce your energy costs by turning lights and climate systems off when guests are not in guestrooms or public spaces. And keeping those guestrooms and public spaces clean can also be made more efficient with work order systems that allow teams to submit tickets, see in-progress and closed tickets, route tasks to team members, and complete preventative maintenance on-time.

Key Technologies in Smart Hotels

So what exactly makes a smart hotel “smart?” What technology do smart hotels use to create better guest experiences and more streamlined operations? Let’s dive into four main types of technology: the Internet of Things (IoT), artificial intelligence (AI), mobile apps and digital platforms, and smart room features.

Smart room controls

  • Voice-controlled devices and smart speakers: Smart speakers can do more than just play music; in addition to controlling other in-room devices, they can provide hotel information, so guests can ask questions like “Hey Alexa, what time is checkout?”

  • Smart mirrors and interactive displays: Turn an otherwise analog guestroom mirror into a digital entertainment center; smart mirrors offer TV, fitness training, concierge features, and hotel information thanks to interactive touchscreen functionality.

  • Smart beds and sleep-tracking technology: One of the latest and greatest amenities for hotels that cater to health and wellness fans is sleep technology, such as Eight Sleep’s smart mattress topper which lets guests control their mattress temperature and tracks their sleep performance.

Examples of Smart Hotel Implementations

Let’s take a peek into some great examples of smart room experiences:

  • Hilton's Connected Room: Hilton offers guests several tech-enabled amenities in their Connected Room, including Netflix and the ability to control lights and temperature from their HHonors app. The Connected Room rollout started with roughly 1,800 guestrooms in 2019 with more Connected Rooms launching each year.
  • Marriott's IoT Guestroom Lab: Set in the Innovation Lab at Marriott’s Bethesda, Maryland headquarters, the IoT Guestroom Lab aims to create the guestroom of the future. Marriott partners with vendors that provide tech like voice-enabled devices to create the ideal smart room. For example, a guest will be able to request, by voice, a wakeup call or additional housekeeping services. 
  • Wynn Las Vegas' voice-activated rooms: In 2016 Wynn announced plans to add Amazon Alexa devices to all of their Las Vegas guestrooms. But guests can use the Alexas for more than just checking the weather and playing music; Wynn is connecting lighting, climate control, in-room entertainment, and window covering systems to Alexa, so a guest can control their room with their voice.


Let’s explore how some leading brands incorporate contactless technologies into their guest journeys:


  • Accor's mobile app and digital key: Accor launched their digital key solution, dubbed “Accor key,” in 2021. Accor partnered with STAYmyway, now under the Operto umbrella, to provide digital key functionality in the Accor app, which is available to use globally. The digital key enables Accor guests to unlock guestroom doors with their smartphones using Bluetooth technology, which will not only make the check-in experience smoother, but will also reduce Accor’s environmental footprint by minimizing plastic key card use.
  • Hyatt's Mobile Entry: Now available at many Hyatt properties, the Mobile Entry program lets guests use their smartphones or Apple Watches as their room keys. Guests can check in through the World of Hyatt mobile app then add their digital room key to their Apple Wallet for easy access.
  • CitizenM’s mobile app: Tech-forward brand citizenM creates a fully contactless experience by encouraging guests to use their mobile app. Within the app, guests can check in and use a digital key to unlock their guestroom door.
