Went there everyday on our 4 nighter. I was there between 4 & 6 and it was never crowded. There us a heavy duty steam room, an "aroma" steam room and a light sauna. There are a few "special head" showers and the "tile lounges". There is a better sauna back in the mens locker room with fabulous (did I really say that?) sauna lounges right outside. Definitely get the pass. You can run up there (as many times as you like, it's unlimited) whenever you have a few minutes. You have to wear a bathing suit, so I just ran in in mine right form the pool area. You're gonna love it.
