I have a set of 4 4-day tickets from 3 years ago - I don't think they were the 'hopper' back then. Each of these old tickets have a min of one day - some have two days left. I also just purchased from AAA 4-day Hopper tickets. When I get to Disney (March 21) - can my resort (CSR) combine these tickets? I don't want to lose any "days" credit - but I also don't want to carry a bunch of these cards around. When/If they can be combined - can I also use the tickets to charge back to my room?
