I travel for work every week, but i only use this app for the hotels. The app started out well for about 2 3 months. Definitely comparable to the rest of the savings apps and accounts. I noticed my (Carrot Cash/in App Coupons) rising up. I tried booking a room. Hopper repeatedly asks if I want to use the carrot cash towards my reservation. I decline over n over. I try Freezing the Price of the hotel. Hopper secretly diverts my Price Freeze. THEN they prices raise all the Prices. I'm done now.
