I have not been to another Legoland, so can't comment. One thing that would definitely be different is the people. Denmark was awesome. People were all very nice and polite. My wife made the comment, "People here are so civilized"

Based on this, It seems lego house isn't at the other legolands, and that was the highlight for my wife and I. It was like a lego science center.
