Anybody think there is a remote possibility that I could "upgrade" the 7-day park hoppers that I just bought to these special tickets? I'm not looking for a refund, but it would be nice if I could get the water park addition without paying more. That way, if the weather is looking good for our October trip, maybe we could surprise the kids with a day at a water park. Unfortunately, DH and the kids have the MYW tickets and I have a Gold AP so I would still have to pay for a single-day water park admission for me, which is why I don't want to tell the kids in advance. If the weather is too cool, I am not going.
