I despise Legoland but my four year old adores it. We were there yesterday and it was empty, but it was also Super Bowl Sunday. In two and a half hours we rode the merry go round, the wooden coaster 3x, the dragon coaster, that horse jousting ride, Merlin’s whatever the heck it’s called, met Lord Wu, rode the water ride, rode the shooting ride, and had a quick lunch. She also briefly played in two of the playgrounds. Everything was walk on! If you hit the park at the right time you don’t need a full day.
