17 Best Hotel Booking Sites of 2025

If you’re a spontaneous traveler who doesn’t mind booking reservations last minute, you’ll love HotelTonight. This same-day booking app helps you to find highly discounted rates, even at peak vacation times. If you’re wingin’ it and booking hotels last minute, this is a great option for you, with discounts averaging between 30-50%.

All the hotel listings are categorized based on their luxury offerings and amenities, as well as price range. You might see boutique hotels labeled with DEAL, meaning the savings are significant. Other hotels are categorized as LUXE, HIP, BASIC, SOLID, and other buzz-worthy words. For example, Luxe means a high-end hotel, Hip refers to popular and trendy hotels, and Crashpad means hostels and budget rooms.

HotelTonight definitely caters to a certain demographic. One of their key messages is “Happy hour is never just a happy hour.” I suppose it’s a good tactic to discourage people from drinking and driving, but it’s a little bit sleazy at the same time. I feel like HotelTonight is expecting you to have the app handy in case there’s an emergency one-night-stand.

Even if you can’t find the ideal hotel deal, you can still request upgrades at discounted rates, which not many hotel booking sites seem to offer. HotelTonight is also purely a hotel booking site—you can’t book anything else here. It’s kind of refreshing.

When signing up, use the HotelTonight promo code JFOSTER237 to get 20% back (up to $50) after your first booking.
