Not going this year, but thoroughly enjoyed it last May.
For those of you who ARE going, two people I would highly suggest meeting are Ashley Eckstein (Ahsoka from Clone Wars) and Peter Mayhew (Chewbacca).
I've been to many "meet and greets" for various sports and entertainment celebrities, and the vast majority act like they want this damn thing over as quickly as possible. Both Ashley and Peter seem as happy to meet you as you are to meet them. My son emails Ashley after every new Clone Wars tv episode to give his opinion, and she responds within an hour or two with her appreciation and thanks. How cool is that?
Now, for what I would like to see? Sounds Dangerous torn down and replaced by a Star Wars restaurant, in the theme on the Cantina. Never going to happen, but a man can dream.
