I don't know if I want to get a hopper or nonhopper promo ticket (the ones that expire may 23) from undercover tourist so was wondering if I buy a non-hopper and decide I want to hop, would I be able to upgrade at the park. I did talk to someone on the phone and they said that you couldn't but thought I'd double check to see if any one was able to. Also, general question about expiring tickets - if they aren't used you can still apply the value paid to a ticket later, correct? This would also apply to these promo tickets I assume. I understand the difference would be huge because these are cheap tickets, but just want to make sure that one would at least get credit for what they paid.
