Smart rooms will be driven by the growing adoption of voice assistants, such as Amazon Alexa. With a simple voice command, guests will be able to adjust the in-room lighting, schedule wake-up calls, and request room service.

But arguably the real benefit is the rich data that hotels will be able to collect from these interactions. Knowing past preferences, the room could be setup in just the right way for returning guests so that it feels like their home away from home.

The personalization trend will also see more hotels invest in streaming services so that guests can watch their own content on the in-room TV. Hotel apps will also give guests more control over their rooms, such as setting their preferred temperature prior to arrival.
