We have purchased a non expiring 5 day park hopper with plus visits for our 9 YO son. My question is, what happens when he turns 10? Do we have to pay more for him, or can he still use his original non expiring ticket, even though when we bought it, he was under child pricing guidelines? We do not plan to use all of the visits on this trip. Has anyone ever had this happen with their childrens tickets? What did you do?
