There are many interesting boats, you can find an audio guide, they will provide a lot of specific information, to tell the truth, it is very happy to see, many tourists come to play.
There is no toilet on board, so please go to the public toilet before boarding. Boarding a ship requires climbing stairs, and then climbing down a ladder to get into the ship. There are lots of interesting videos and gift shops. The video lasts about 40 minutes. You can also look on the deck.
