Very good experience, the scenery is beautiful, you can have a panoramic view of the whole Sentosa. There are two lines, you can get on and off at any station, but you can only get on the bus at any station. Of course, if you don't get off the bus, you can always sit, and no one will catch you. Both are ring lines, one line can see the beach and sea views of Sentosa, the other line can see the aquarium and the world.
