Paid parking makes me so cranky, but it's because places always jump straight to paid parking instead of doing any of a million other things they could do to try to get fewer people to drive to the mountain.
Have you considered... convenient shuttle routes to popular lodging? A seasonal bus system that actually runs enough to be useful? Real incentives for carpooling? Perhaps give consistent carpoolers meaningful pass / ticket discounts instead of free socks (A-Basin does free socks, it's so ridiculous). A place to get dropped off by shuttles / buses that isn't a long slog to the lifts? Free lockers for people who don't take their car to the mountain (so you can easily wear your Transpack on the bus and boot up at the mountain)?
Paid parking would be palatable to me if they used the parking fees to subsidize any of the above things. IMHO when mountains contribute to a local traffic fiasco these kinds of things are the least they can do, but apparently the mountains don't agree with me.
Paid parking basically says to me "we want more money", not "we care about fixing our parking issues".
