When I arrived at this hotel around 23:30, I needed to give booking number for self check in. But I tried 100 times but i cant do further anything. No booking number existed. I checked my email in handy and refresh login and checkin, but it didnt work. I stayed 1 hour front of hotel. So i called the number of this hotel, cant reached anybody. It was not Expedia's problem, but hotels problem. The night service person was asleep at that time!!!! I was so afraid in middle of night. This experience is still horrible.
