I already purchased 3 seven day MYW tickets with the hopper. Can I exchange them when I get there for 8 day tickets or would it be a problem? Thanks in advance for any answers.
You should be able to. We exchanged our 7 day tickets for 10 day tickets. I think you can do this as long as the tickets you want to exchange for cost more then the tickets you upgrading.
I changed (upgraded my tix from 7 day MYW PH to 10 day PH non expiring at AK guest relations. I think you can only do this at guest relations, though I never bother to ask at the front desk. We only used 4 days so now we have 6 days left. It cost $462.20 for 3 adults and 1 child for the non-expiring option and 3 extra days.
