I used this app twice for hotel reservations & the first time everything was fine. The second time not so much. I made my reservation on March 3rd for the 11th-13th & had to pay right away. When we got to the hotel we were told that our card was declined. I showed them my card approval & my confirmation from Hopper. They proceeded to tell us that the reservation was made on March 9th and the card, which had to be Hopper's card was declined. There is no contact info on their app! Do Not Use!!!
