Legoland Florida ?

We are trying to get our Fall Break plans together and looking to do something new in Florida ! We have been to Universal Studios and Disney more times than I can count, so after doing some research I found LegoLand. My 5 year old son is obsessed with ALL things Lego, so this might have to be a theme park to try but Trip Advisor has mixed reviews. I'm thinking this will be a GREAT travel review for the blog....
