I have old tickets from before the AK park opened. These are 5 day all in one hopper tickets. They each have 2 days left on them. My question is, are they still valid for the water parks? I think that these tickets did not use the current 'plus' terminology for the water parks, but were simply valid for 5 days at any of the available parks. I know that I can have the tickets checked at the guest services once I get to the parks, but I am trying to determine how many new tickets I need to buy. If these still are valid at the water parks, I would not need to purchase the plus tickets for my next trip. Does anyone remember what the rules were at the time these tickets were on sale. The date on the back of the tickets is 12-97. I had misplaced the tickets on my last trips and recently re discovered them.
