The park was that packed for Spring Break.... The summer seasons, Xmas and Spring break our the busy times.
The parks are not that busy when it is not a peak season. The best time to go to ANY park down here is Jan, Early Dec and Sept.
The reason why the park seemed empty at the beggining of the day is because everyone is at Harry Potter...
So if anyone is planning a trip down here and go to IOA go to Harry Potter last!!!!! Spend the last 2-3 hours of the day there right before park close!
You will thank me! I now live down here and I go to the park all the time!
