Do you know about Hopper? It is an app available for both iPhones and Android phones, and it does a great job of finding low-priced fares and also of predicting if airfares will increase or decrease between when you researched fares and when you plan to travel. It’s not a website, though. It’s only an app.
Their newest venture is predicting if hotel room rates will rise or fall, too. Initially they are trying this with New York City hotels. If successful, they’ll roll it out to other cities as well. Part of their hotel service is sending their own people to every hotel to provide a truly consistent and fair rating/review of each hotel. You can read the write-up about Hopper here. Sounds like a great idea if they can get this up and running well. Are you a Hopper fan? Are you going to try this in NYC and see how it works? Let me know!
