Thank you for the kind words and constructive suggestions.
Nothing wrong with shifting south - I rode past Little Switzerland a couple of times during the week. Primary concern with that specific venue would be the cost. A quick call to confirm pricing - October is considered the "peak" season and rates. So off peak (September) rates would be $159 weekday / $189 weekend with the possibility of a 5 to 10% discount in a group rate according the friendly lady I just spoke to. A typical EOM weekend (Thur/Fri/Sat nights) would run $507 plus tax for lodging. This would be an excellent venue, but bring a premium price as well. There could be venues in or around Asheville, its worth exploring.
Banquet meal (@FredW) - we've used outside caterer's twice since I've been involved with EOM. Hendersonville, NC and Wytheville, VA.
In both cases, the hotel we were at did not offer in house catering, forcing the use of a local vendor. There were issues with both. In Hendersonville, in the various conversations had with the manager, he failed to mention that he stopped accepting credit cards until 1pm the day of the banquet. I hustled back to the hotel, moved funds from my personal account and had them wired via western union in Hendersonville so I could pay for the meal. This was transparent to the group. Point being, you're correct, the best option is to find a hotel that has a restaurant on site with a banquet catering service provided. Lewisburg, Cumberland Falls, Maggie Valley, Johnson City all fell into this category.
With Wytheville, there were no hotels with banquet / conference rooms to handle 100+ people. There is a convention center that was available at a cost that could handle more, but you're in the same boat with catering, plus having to ride / car pool there. There seemed to be a significant amount of adult beverages consumed before the banquet, so riding to a dinner venue is out of the question.
I'll toss this out there - for anyone making suggestions for a venue, here's the starting point - 100+ rooms, conference room / banquet space for 120+, Gas / Grocery/ convenience stores nearby, a restaurant/bar/lounge is a huge bonus, free hot breakfast is a plus - all this near enough scenic riding to support 2-3 route loops.
