After getting back to our room at 1am we were locked out of our room all night because of a dead battery in the key card reader. We were told we had to wait until 7am for maintenance to show up. Hotel staff put us in a different room in the meantime but we didn't have any of our luggage or belongings. This was incredibly frustrating and inconvenient. Completely unprepared and clueless management of a very large hotel. Its mind-boggling to me that no maintenance staff is on call on a saturday night. The busiest day of the week for a hotel. Or at least call a locksmith for god's sake.
