Mallard, you have excellent points! My only two times there, I drove home after a Friday at York. In the effort to save money, that is probably dumb in this case. The trip takes me about 5 hours with stops included in that. Why not reserve the extra night, and I can cancel one just as easily as I can cancel the whole trip if need be?
Enabler is a good term for your words. In effect the discussion back and forth helps those involved make the best decisions whether it is building a layout or planning a trip to a show.
