While my husband was on a business trip, I took my children (5 and 8) to CoCo Key for a mini-vacation -- we were to spend the day at the waterpark and then spend the night at the hotel. We got there about 3:00 and it was already packed -- super noisy, all chairs and tables taken, no lockers left, tubes and life jackets strewn all over the place, bigger kids pushing their way onto the slides. The two biggest cons, though, were the fact that there is really no place for kids to swim, and, even though it was packed with people, it was very, very cold (this was in mid-April, too). I doubt that it was even 80 degrees in there, and the water was tepid, too. We were only there an hour before my 5-year-old was shaking uncontrollably and had blue lips. We couldn't wait to get back into the hotel room and under the warm shower water! Once we were upstairs, neither child wanted to go back down into the park, which is saying a lot about how uncomfortable they were, as they can spend all day at a swimming pool.
