Thanks for starting this thread, Deb. We're not cruise fans, or big city fans, either. We'd probably avoid that one. We surprised ourselves with Chicago!
Our ideal would probably be an old-fashioned Spyder rally, much like the BMW and Goldwing folks do. A few days of camping (with nearby motels for those who prefer luxury), some good food, gathering together and conversation, some seminars or presentations (maybe they could bring some of their museum exhibits), and a vendor area. Show some movies in the evening, roast a pig (or seven). Add a few organized rides (maybe to a great restaurant for lunch) and some suggestions for "self-guided" tours. It works for the rest of the touring crowd, I think it would attract me.
