There's A LOT to see on the convention floor along with the panels on the 4 stages that's not Hall D23 (now Honda Center) presentations.
IMHO, the floor is a lot more representative of Disney magic than the premier shows. There's official showcases from different parts of Disney along with 3rd party vendors for their merch. Lots of photo ops, signings, and really liked the small panel guests that happen throughout the days at each showcase.
Then there are the smaller panels too that have a lot to offer. If you're a legacy/historical person, there's LOTS of those really nice panels too.
It's a great Con IMHO. Not crazy like San Diego Comic Con that's happening just a few weeks earlier.
