We are booked on a package for our upcoming trip that includes a MYW park hopper ticket. We are thinking of upgrading them to AP with the DVC discount. Can I do that on site or does that need to be done in advance? TIA!
Easy enough to do at a park. We did ours at Epcot's International Gateway. It does take a few minutes to do, however, so I'd recommend doing that sort of thing when there aren't that many people at guest services.
