"I booked a king room, got put in a double. Hot tub wasn’t open. My husband’s room key didn’t work so he was locked out of our room (I was sleeping with phone on silent). Since we were put in the wrong room, she would not give him a key to the room we were actually in and did not call the phone in the room to wake me up. Woke up to my husband beating in the door since he could not get another key for the room we were staying in. "
