Hi - we're going to Disneyland in July for a quick 2.5 days, staying at DLH. We're WDW regulars, and while we went to Disneyland 7 years ago, I'm still a newbie there.
My son is neurodivergent and probably getting a bit old for characters, but he was absolutely certain he still wants an autograph book and wants to meet characters. We went through who was listed in the app, he first wrote down all he wanted to meet, then due to the length, I had him prioritize the "musts".
It's still a lot of characters to meet.
We explained that due to the time and the other stuff we want to do, we probably wouldn't get to all of them.
That's a long preamble to my questions -
What is the character meet and greet situation like?
I know not everyone is out regularly and to check the app, but is the app accurate?
I know not everyone has a line like WDW, but does anyone? Is it all a free for all?
Do they mostly sign (I understand not everyone can)?
