we were there this year from 3/16-20 to suprise my dd for her 5th bday. it was very crowded, we didnt even go on many rides, the wait's were just too long and the kids 5 and 1 weren't into waiting so long. we mostly played at the pool and on the beach. from talking to people while down there, it seemed like there are alot of people on spring break at that time.
