Hotelsbyday is a hotel booking website and app that lets you book rooms for just a few hours at a time. Whether you’re looking for a place to nap after a long flight or refresh before an important meeting, it offers thousands of hotel options in locations that suit your needs.

Its founders – Yannis Moati, Nathan Stevenson and Brian Dass – come from luxury hotel and travel technology backgrounds. They drew inspiration from single purpose apps like Uber and wanted to bring this kind of functionality to hotels around the US.

They started by approaching hotels and showing them how they could take advantage of their unused inventory. They’ve now made 250 reservations at dozens of hotels in 10 U.S. cities, with the most popular times being from 10am to 4pm. It’s a win for guests, who get bargain-priced rooms, and for hotels, which are able to increase their revenues without the incremental costs of housekeeping and overhead.

HotelsByDay: Revolutionizing Travel with Flexible Daytime Hotel Stays

But the big challenge remains convincing larger hotel chains to sell day stays. They are used to pricing their rooms for overnight stays, and the HotelsbyDay team is trying to get them to change that. To do this, they’re working to integrate with the existing channels that hotels use to manage their reservations. Once this happens, they’ll be able to offer their service to the entire pool of hotels globally. For now, though, they’re still relatively regional. Only properties in the United States and Canada are available on their site.
