Your post brings up another good reason why they are nuts if the expand the playoffs.People just don't have the coin to keep traveling to different,far away venues - buying tickets for the game and a plane ride to/fro and perhaps rent a car.The wonks just don't get it
all these appearances for bama in last decade, i've made 2 trips for post season games.
first was pasadena, cause it was first time in my adult life bama had a chance to win title, no one had a clue we'd go on this run, and so i thought might be my only chance for at least a long time to go to a game like that. plus i'd never been to cali and it's the rose bowl. put a big dent in knocking off bucket list things for me that trip. good times.
second one was vs clemson in sugar a couple years ago. and only reason i went then was i have a brother living in nola and free place to stay, and we got tickets relatively cheap.
having said that, if some of those games were in tuscaloosa, i'd have definitely gone to more of them.
my point is it's a double edge sword. there's going to be people that can't/wont go to the traveling games, no denying that. but you'll pick up a lot of people that don't go to those anyway. stadiums will still be packed, so schools won't be losing money. the cities, on the other hand, might suffer a little. but not really, cause right now, after november, very very few college towns have vacationers anyway.
