Any pools in Orlando, FL to avoid?

Going there next week for 2 weeks or so, need to get in at least every other day. I see a ton of "places to swim" but any advice as to what to cross of the list would be great. I don't necessarily need a team to swim with, and am looking for early swim times (6am-ish) as to not interfere with the theme park excursions for the family :). I'm not a YMCA member so will probably avoid Y's to begin with as they won't let you in without a valid card from your "home" pool.
