Yes, I understand, thus my original post asking if spots become available. Probably doesnt matter to you but for others potentially in this situation, when I just logged onto the Cruise planner it showed "2 spots available" but I couldn't select them (someone else must have had them in their cart) so clearly spots become available. A couple minutes later it shows "sold out." I'll keep checking. I'm happy with our low fare for balcony stateroom and I know we'll enjoy our time whether we get into the water park or not.
