Pretty disappointed with the hotel. We checked in on a Monday. I guess we were in the main section of the hotel, on the 11th floor facing the pool. We headed out pretty much immediately. Came back to the hotel around 9 and our room was extremely hot. We thought we just had the air on the wrong setting, so we fixed it and headed out again. Got back at 4 am and our hotel room was around 80 degrees, so we called maintenance. They responded right away, checked out our unit, and said the air was working properly. At 6 am, all four of us woke up, miserable. We went to the front desk to change rooms but were told every room was full. Our only option was to switch to an upgraded room the next day in the HRH tower, but we would have to pay for the upgrade. They refunded the day fee ($24) and we switched rooms the next day at 11. The new room was improved but I still find it unacceptable that we had to pay a $80/day upgrade when their room was the one with the issues. If they didn't have an equal room with a working air conditioner, we should have been upgraded free of charge. While we were able to salvage the trip, I will never stay here again!
