  • Chi Lam 29 Jul 2018
    it is a good water park for child and family, nice games but a lot of people query, takes a hour to pay a game, there is not enough workers in the park.
  • Miranda 24 Jul 2018
    very good for family with kids.
  • Wong 23 Jul 2018
    A small place inside a single building with a lot of people. Need to walk up several floors. Everyone must put on life jackets in order to play and few eating places. No space for sitting or resting since everywhere are beach chairs which have to paid. We did not enjoy it at all. It cannot be compared to Caribbean Bay which is big, clean and fun. Don't waste time going there.

    It was a nice place for kids to play and very fun. It might be better to have more variety on food and snacks. We will come again.
