Tivoli Gardens, Copenhagen, Denmark (4,396,000)

Opened in 1843, Tivoli Gardens is now as much a concert venue as it is an amusement park. The Copenhagen Jazz Festival takes place on the open-air stage, and there is a different rock concert every Friday night. But plenty of people still come for rides like The Demon, a 60-foot roller coaster with a series of stomach-turning loops.

From the Statoil Traffic School, where one can earn an official LEGOLAND driver license to LEGOLDMINE, where gold-mining wannabes can pan and melt gold dust to make shiny coin souvenirs; this park is fit for a prince— as evidenced by the recent visit of two year old Prince Christian of Denmark.
