Hi! This will be my first D23 Expo (or any Convention like this, I've never done Comic-Con or the like). Is there a general policy or unwritten rule as far as saving spots in lines goes? I'm going with one other person, and there are several times where one of us could wait in line while the other does X activity; is that something that's frowned upon, or is that pretty common / acceptable at the Expo?
I just want to make sure I don't do anything to ruffle feathers. Savings spots in line bugs me at the Disney Parks, but unsure of what's acceptable at events like D23.
