We love water parks and this was part of the reason we stayed at the hotel. But this one just didn't click with us. Rides are all intertwined, it was so hard to meet up again if people went off on different rides, and even the lifeguards couldn't really tell you where riders would come out on the other side!
The other problem we had was injuries - we all got bruised or bashed on the stone walls, and we saw the medic dealing with at least 4 other people. One poor Russian lady sat next to me for 10 mins waiting for the medic with blood all down her leg - I made her elevate it on her rubber ring and got her some paper towels from the ladies loos!
So my advice would be take it easy, take some plasters with you, enjoy Shark Attack which was hilarious, and stay together as a group!
By the way, if you're staying at the hotel, you need a blue wristband to get in, which you get from the 1st ticket window on your left. And to view photos after you leave, go to the entrance to the Lost Chambers aquarium and scan your other, yellow wristband.
