Hello! This is my first time on here so if I do something wrong or put this in the incorrect section please let me know 
I wanted to ask the past D23 expo goers for tips on when to arrive and just for tips in general, as I've never been before.
I originally wasn't going to go, but then I saw the recent news that there would be Kingdom Hearts III news, which sealed the deal for me (if I'm able to get my friend to come too, anyway). The event is at 11AM in Hall D23. As long as I make it into this, I'll figure out the rest of my day.
So my questions for all you hardened veterans would be...
1. When should I get there to get into this event? I can't be there very early, because I doubt anyone I would bring with me would be interested in camping out or being up at the break of dawn. Luckily, I live about 30 minutes away from Disneyland, depending on traffic.
2. Can I use my DL pass, which has parking, to park in the DL parking lots where you're bussed over and just walk from there?
3. Is the shopping aimed at collectors or will it include some more casual merchandise? Or maybe the more important question is if I can even get into the shops, lol.
4. In general how early should I get into lines for everything?
5. Any recommendations on what to see, what to avoid, etc.?
6. I've heard about people getting to meet some of the stars that come to the expo. How is that organized? Is there an official meet-and-greet?
Big thanks to anyone who answers my many questions!
