Men's locker room was also a cool-down area, which was really nice. You don't need to leave your sea pass card to get a locker, as the lockers have combinations. No key.
The men's area is free of charge. The sauna was pretty decent and warm, dark with two levels. Holds about 6 to 7 guys comfortably. The steam room was very nice! Built in seats (fiberglass?) around the inside which would seat around 12 or 14 guys. The steam wasn't too intense but enough to get the job done. Three showers in the men's area and a water fountain. Lots of fresh towels and the service was good.
The Lotus Spa area was very nice, we enjoyed it. I think it was $190 for 15 days, but we were in a suite so it was complimentary. Heated tile loungers, 5 or 6 and they were never completely filled up. One large Turkish-style steam room, one aromatic (2-person) steam room, two rain showers and a pretty large dry sauna. Directly outside is an "adults only" pool with loungers (free). Directly adjacent to the free men's locker / steam area and only a few steps from the pay Lotus Spa. I think this was one of the best set ups. Enjoyed it!
