I have used the app for two hotel reservations, received confirmation emails, and then, when I arrived at the hotel, was told they didnt have my reservation in their system. Yesterday, after being on the road 10 hours, I exhaustedly arrived at my hotel and was told I didnt have a reservation. I called Expedia, as did the hotel, and was told they would fax (?!) my reservation immediately. 30 minutes later, nothing had arrived. I finally cancelled my Expedia reservation and made a new one on the spot with the hotel--at $10 cheaper! Ill never use this app again.
