If you are not with children, it is recommended not to go to this attraction. There is also a submarine, ship, are old objects that were retired many years ago. At the same fare, the venue does not accept individual visitors, such as the ship museum, groups can enter, individual guests can go in and say not open, which is very annoying. Other venues are a bit closed, and some are not allowed to visit. Fortunately, 1.3m Children don't need to buy tickets, or it's really a loss, money is not a problem, and the price/performance ratio is very low.
