Here's what happened to us...when my family of five arrived at the Comedy Club in June with our old passes ready to use a plus feature, they had to send us over to the Adventure's Club to validate it and get our wristbands. They explained that they are the only ones that have the old machines anymore to accept these cards. I'm not sure how the water parks will do it, as all the entry machines are for the newer tickets, I would probably go to guest services at that park and find out first.
