So - We had 2-day park hoppers for 2 people. Now we need 1-day single park for 3 people. Will that even work? Price is about the same, but not sure if cheaper or more expensive. I thought the credit was just money to use on future tickets. That sounds like not the case, which is super irritating. And I don't have hours to sit on the phone because of work, can they do it over chat?
