I like the concept but it looks like vaporware based on the site. There's no description of how it works or even email field to receive a notification when it launches.
Also, "Hotels Tonight" might not have been the best analogy as deals aren't offered. It's more about getting notified about openings at restaurants that are hard to get a reservation at.
