text: actually we do call these "theme park" in italy, they are called "luna park", in reference to the luna park in Rome and ultimately the historic one in New York.
  Do you have better tagging? leisure=playground with fee doesn't seem to meet the expectations, it is not a gaming arcade either, or is it? Sometimes (often), there are also mini trains, and similar attractions, although very small, still a kind of mini theme park. What do you think?
