It is interesting that you aren't welcoming to 2ball play during busy times
Bottom line, its not about how friendly a club is, its money you are really talking about.
I don't know about others, but all things being equal, I would join the club with multiple starting points and shorter (boozers loops) routes available. I am always impressed by courses which offer a lot of choices. I was just pondering Prestwick's routing the other day...an incredible amount of options which doesn't require hardly any extra walking...of course...I always believed that the best split back to the house is not 9-9, but 4 or 5 and 13 or 14....and Prestwick nails it!
