My only issue would be the fact that some people (due to occupation) need full-size trucks/SUV's, so why should they have to walk farther. Other than that I could care less.
Why should people riding a bus to a ski area / sporting event, etc have to walk further if that's where their designated parking is?
What if the bus parking is actually closer and someone in a Prius decides, hey, I'd like to park up close and parks in the bus spot.
I guess I just subscribe to it being a private business and they can run it how they choose. If I don't like the rules, no one is forcing me to do business there.
