The smaller conventions are much better all the way around. I've had the opportunity to meet John De Lancie, Wil Wheaton, and Chase Masterson all in more informal situations at conventions, and it's much more fun that way. Actually ran into Chase Masterson at Quark's bar at the Vegas Hilton (I soooo miss that place) as she was setting up for an autograph session. The group I was with (3 of us) spoke with her for a few minutes. Didn't ask for autographs or anything, it was just fun to talk. She was extremely personable to talk to. John De Lancie was speaking at a convention that was very small, and basically sat with the group instead of being up front. It was more of just an informal discussion than the typical celebrity standing on a stage and telling a story or two. It's interesting to hear their take on the characters, but I agree that talking to the writers would probably be even more interesting in some ways. I haven't had that opportunity yet.
