We're from NE and swimming during the winter down south is fine with us, although the natives do give us strange looks! The pools are really quite warm, in fact when we were there during a cold spell in late Oct.'99 people were in the pools to get warm!! Now, a warning.....my dd suffered horrible that Oct. after swimming in the pool. Seems that there are some people that are really bothered by over-heated chlorinated water. Their eyes get very red and feel like there are red-hot pokers in them. Poor dd cried for 2 hrs. Probably did her good in that it washed the chlorine out! She wears glasses, so we got her a pair of prescription goggles. Now she swims pain free!!
