Legoland Billund is made of pure awesomeness (and lego). But if I had to choose, I'd choose France. Easily done by train and you can be home in a few hours. If I go to America once, it won't be for Disneyland.
SATAN KLAUS! MWHAHAHAHA! Anyway, I don't think you like Lordi much, do you?
Terror Train is still better.
