Goodies so far:

I also got my copies of What Moves The Dead by T Kingfisher and Red, White & Royal Blue by Casey McQuiston signed, but I already owned the books.
The place was packed, more that it's typically been in my experience.
I went to the Plot and Pacing Panel:

N. E. Davenport, Isa Agajanian, Casey McQuiston, Charlie Jane Anders, John Scalzi and Ryka Aoki. Amazing line up, but that many authors and that broad a topic, it was mostly just going to be some random chatter. During the Q&A session some guy asked if fanfiction was an acceptable form of writing practice or does it hurt your own voice too much. Then John Scalzi went 'Fanfiction writing is writing' and the audience cheered.
Weirdly, it was the tag end of the panel before that was more interesting about writing. They were having writers submit 'back of book blurbs' for their projects for critique and actually, the people running the panel gave interesting feedback.
Next was Sidekicks and Side Quests:

T Kingfisher, Terry Brooks, Gabriella Buba, Rachel Gillig, Aiden Thomas
This panel was more unfocused. Before the panel started Terry Brooks was walking around thanking people for showing up to his panel, but I had no idea who he was. I actually thought he was just a guy making jokes and not an actual panelist. Between Terry just giving advice that may or may not have anything to do with the topic, people being excited to be on a panel with Terry and T Kingfisher answering a question on research by explaining in depth the purpose of caterpillar inflators while Aiden looked like he was about to tap out... yeah, amazing line up... but if you wanted to go to learn about writing in general or these topics in particular, lol no
I roamed the exhibit hall a bunch. It was amazingly crowded.
