Well it was Nov. 2001 when we were there and the hotel was very new. We loved the hotel! The rooms, free breakfast, location etc. However the only reason we haven't been back is that the pool was like an iceburg! We couldn't get in past the steps. We are from il. so we are not cool weather wimps at all and it was actually one of the warmest Nov. trips we have ever taken and we still couldn't swim in it. Temps were about high of I would guess high 70's low 80's. We were there for one week and we never saw anyone in the pool. Lost of people in the hot tub though. One morning while eating a late breakfast we watched a family unload all there pool stuff onto chairs and sit and lather sun lotion on both kids then when they went to get in!! Well they picked up all there stuff and left!
My DH went one day and complained to the manager and he said it is not a heated pool and that was that. Well of course we didn't expect he could do anything about it but we wanted to let them know we weren't happy to be there for a week and have non park days planned for swimming and not be able to swim! When the temps outside were definatly warm enough for it.
Now if you are there in the summer this may not be a problem for you. I don't mean to scare you off but we haven't been back because of that and my DH loves to stay at Marriott hotels because that is where he has to stay when he travels for work and we like to earn all those points!
Maybe you will get more responses or call the hotel directly and ask them about it.
