The AC was working. When we checked in we were told that it was just the “lobby”. We later learned that the person at the desk was told to lie and they knew it was a problem throughout most of the hotel. We had reserved/requested an upgraded room and even though the hotel was almost empty we were not given that room. We had a oceanfront view room however we had to keep the drapes closed to try to keep as much heat out as possible. There were very few lights in the room, so we were stuck in a hot dark room. It was miserable. There was supposed to be valet parking however we only saw a valet once. I would NOT recommend this hotel! We tried to move to the hotel next door (Four Seasons) however it was full due to the World Cup team from Portugal staying there. Although the Tideline has undergone a remodeling recently it is not a high quality hotel. There is a saying about putting lipstick on a pig….Don’t fall for the pictures. DO NOT stay at the Tideline.
