It's been a couple of years since I've been, but I think I remember there being two. One by the pool down by the beach, and one up the stairs from the minearl pool. I think you couple fit 2-3 couples maybe? Altough they were almost never in use because we went in August and it was hot.
I beleive there are 3 (we just got back on Saturday)
One above the mineral pool, which is VERY hot, and I would guess seats about 6?
One by the main pool, seats a few more maybe 8-10? and then one over at the AN beach which seats 6 I think. We used the AN and Mineral pool ones, all very nice, very quiet, and was not anyone in them when we used them!
One hot tub near the mineral pool- up some steps and hidden in the trees. You could probably get five or six people in the tub, but it is a quiet, romantic area perfect for two.....:-)
One hot tub near the main pool/ main beach. Once again up a few steps and hidden in the trees.
One hot tub beside the AN pool on SSB- out in the open, probably could get 6 people max comfortably. (inside the cave in the AN pool, there are also seats and jets- but not a hot tub, more of a cool, refreshing area to get out of the sun!)
One hot tub outside the hibiscus cottage- but this is private only for the cottage guest I believe....
