Coco La Palm hot tub is VERY hot, and that's unusual, especially on the strip and not including the big AIs.

Actually, even a lot of the AIs like RIU, the hot tub is not hot (Couples was blazing hot, though, it even has a sign that says its 103 degrees.) It took several week-long visits to RIU Club before I discovered there is a hot tub there in the spa near Building One.

Treehouse has a pretty hot jacuzzi, too. Samsara is always cold, though the bubbles usually work.
