(Yes, I did a search, but couldn't find what I was looking for. )
Where can I upgrade my AP to Premier? On the Disney website, they say the Passes can be purchased only at the ticket booths, but say nothing about upgrading.
Do I have to go to Guest Relations outside the Park? Or can I just go to Plaza Pavilion? Or do I have to go to the ticket booths to do this?
Thanks in advance!
