Awesome. The local LUG (Lego User Group) is doing a booth there this year. Come check them out, some amazing builders! GFLUG -Greater Florida Lego User Group
Also, Joe Meno (Author of Cult of Lego and editor of BrickJournal) will be doing a book signing at Legoland Florida Sept 1st. I know he's also going to be at the convention, but has a signing at the park. Should be a lot of fun!
