Best/worst coin show venues?

In your experience, what are some of the best and worst venues for the major shows? I have been to plenty of local and regional shows, but not a national show yet. In my research, it seems like the World's Fair of $ wins due to it's proximity to a major airport and better accommodations attached. The one in Houston look abysmal from here.

The New York International at the Waldorf is too broken up (among several rooms) for my taste. Central location, though.
Check out the Southern Gold Society
