Yes we went to the jacuzzi and sauna rooms and they were coed at the spa. Since we had premier they were free for us to use (the jacuzzis were not hot tubs) but I am not sure how much they are to use if you are not a premier member
It was 20 a person for us for an hour of anything we wanted to use in the spa facility. We just decided to tack on a 30 minute massage for that price since it was only around 35 more a person and they let us use any of that stuff for an hour as well as the 30 minute massage. I felt it was worth the price and so did the wife. It was a nice chill way to spend a cloudy afternoon.
