Went to LegoLand in Windsor, UK back in 2000 when I was 12 and it was just about the best thing ever haha! Absolutely amazing though, some of the models actually moved ie; changing of the guard at Buckingham Palace. I think that Kennedy Space Center is now there
I actually got my first drivers license at LegoLand... at the driving school, driving "lego" electric cars around a realistic track haha.
