Susan,
No gym on sight. We did not use the chairs & umbrellas as we sat around the pool area. I would hate to guess on that & be wrong. The beach in front was fantastic. Clean, wide & no boats out front. The pool water will most likely be more tolerable when you are there, as the evenings won't be as cool. We were on the 3rd. floor of the Reef building. You will probably not feel cramped with just 3 of you, although 3 in the kitchen at one time won't work. I believe there is some work going on inside of a few of the units, but you could not hear or see any of it. So absolutely no distraction there.
Wicky's was a really nice bar. We really enjoyed it. If you want me to email some pictures, just send me your address.
