We love Water World and live nearby. Our family came to visit and we decided to try the new valet tube option. It is $48 for every 4 people so we needed two but it is worth the money and then some! You get 3 rides unlimited and 2 of the super crowded popular rides one valet each. We waited literally 0-5 minutes whereas the other people (who were not happy about us zooming by them in line!) waited between 1-2 hours!!!! Also if you have kids with you (we had two) it is so worth it because you don't have to carry any tubes or rafts. You just walk up and the staff gives you the raft at the top.
Since this is there first year with this feature, I hope they will include more rides or more times on popular rides in the future. Still, we got to do a lot more of the other rides that didn't have valet because we weren't spending the whole day waiting on line. In short, valet it!
