Check in was a breeze. We did this at Grand Ave. Walked up around 5:45 and there was no wait.
Oga's is supposedly dead during the event. Not a surprise because as has been said many times here, there's nothing party related to get people in. I'm confident the missed revenues here will at least get people asking the right questions and maybe lead to changes next year.
PizzaRizzo still closes at 5 and later reopens with their special menu. I thought it'd just stay open after 5 but I rolled up and it was down. Had to cross over to Catalina Eddie's for the kids.
I can't recommend enough that AP holders or people with hoppers get in early to enjoy the park. Lines are long so we've only hit stuff like First Time in Forever, Epic Stunt Spectacular, MV3D, Santa meet, and Oga's. I think easing into any Disney event is a more enjoyable experience, it helps to have time to decompress from transportation, check in, etc.
Also, maybe avoid plaid. I didn't consider my outfit choice until a real Plaid teased me. I helped a few with Fantastic questions and it's been fine.
They made an announcement over PA system when park closed that tickets are still available.
