Great for families with kids of all ages! The roller coaster is actually quite fun, however I personally can do without the 4D rides. They were not what I was expecting and if you have a sensitive stomach I would avoid them. A couple of the rides were shut down while we were there so that was quite a bummer for us "big" kids.
Pirate ship and the water ride are sure fun for the kiddos and even though there is not much for "big" kids its a great family attraction for Vegas.
