Along with other computer-generated advances in travel, it was just a matter of time before this innovative app broke upon the scene. During this holiday season and into the new year, savvy senior and business travelers not tied down to specific schedules should look into it. The service finds choice hotel rooms at heavily reduced prices for same-night occupancy when business is slow.

So far, the growing list of hotels includes 150 destinations in 12 countries in the Americas and Europe. New-listing deals may appear on the app as early as 9 a.m. every day. When planning quick travels, check out hoteltonight.com frequently before being required to pay full rate.
