Odds are you aren't going to get something that works for everyone....
Maybe the best idea is to start a category called, "We're goin to"
Then, for instance at the NFR, we could get someplace to have dinner one night, same for Denver, ect....That would move the get togethers around and give people a chance to say, "Oh, I have always wanted to go to ____, let's go"
Just a thought,
