Along comes DealAngel, a hotel-comparison site. It analyzes a hotel's historic pricing, and measures its upcoming rates against those of its competitors to find legitimate hotel deals. The start-up often does a better job of pointing you to great hotel deals than does Google Hotel Finder, and can highlight room bargains that may be buried in Kayak's results. DealAngel currently crunches hotel rates in about 150 cities in the USA, Canada and Mexico from more than 30 hotel websites, including better-known ones such as Booking.com and Hotels.com to more-obscure sites such as Olotels.com and Onhotels.com.
