I've been there many years and am going again this year. It sounds like you've got everything down that you'll want to see. Of course the show itself is Sunday morning, get there early. The cars are NOT under tents, only the auction cars are.
For those in the Northeast there is the Greenwich Concours in Connecticut. Not quite the level of Pebble Beach or Amelia Island but it is "up there" as far as exotic/expensive/rare/unusual cars are concerned.
Amelia Island Concours d'Elegance was awesome. Cars, cars, motorcycles and more cars.
I did get to talk to Wayne Carini, nice guy. He won at least two awards. I didn't watch the entire awards ceremony. Keith Martin, Donald Osborne, Tom Shaughness, Dale Walksler were all there too. Talked to most of them. All nice guys.
Had a tour of the RM Auction by Andy Reid and Tim Suddard of Classic Motorsports along with an RM rep. whose name escapes me.
