We are in the process of planning our next trip to the Fort and trying to decide on when to go in 2010. We are considering going the last week of June through the July 5, 2010. How crazy are the parks during the 4th of July? I know the temperatures will be very hot (we live in Florida) but are the crowds as heavy as Christmas, New Year's, Easter and Thanksgiving? We have been to Disney during all of the holidays. Also, what are the 4th of July activities and events at the Fort?
