Arrived at 10 pm and was told my room wasn t ready. I had just flown in from the east coast so it s 1 am to me. I was told I would have to wait at least 30 minutes.
I had checked in on their app earlier and notified I would be there around 9.
It sure how they don t have a room at 10 at night since check in was at 3.
