Just got back from Legoland FL.  Left on 12/26 and came home on 12/30.  We had a great time at the park and spent some time at Downtown Disney one day.  Stayed at Cypress Campground which was just up the road from Legoland.

My son is 6 and he loved it.  Especially the Imagination Station (where you build and race cars).  I think he could have stayed in there all day.  The pirate show was good and the fireworks fun.
