I wanted to comment about the "it was wet and it shouldn't have been". The drink station is right next to the pool, isn't it? That's what I remember anyway. And, being near a pool and near a drink station that must get hosed down a lot to keep it clean, if they cordoned off the area everytime it was wet, it would rarely be open.
I am truly sorry for your accident and cannot imagine you nad your family's disappointment for your vacation being totally ruined.
