Passholder benefits while visiting with a day ticket?
I'm planning on multiple days at EU with a multi day park to park ticket as it gives me more flexibility significantly below the cost of multiple 1 day AP add on tickets. I wanted to know when I go to EU do I not get the AP discount for food and merch since I would be using the multi-day ticket? By extension if I then visit studios or islands will that cause issues with having two options to scan me in? I also have AAP so I'm wondering if it'll then say I'm not in the park if it's attached to my AP or if it's attached to my universal account.
I know this seems convoluted, I just wish they would just give us multi-day EU as an add on (for money of course) so I wouldn't have to do this. Everyone else is getting EU at a reasonable rate for multi day except APs that are still getting fleeced a year later. Make it make sense.
