although to counteract that, the basic AP has block out dates which include weekends during peak seasons. of course you can buy a blockout pass or a PAP and not have to deal with that too.
the real question is how many PAPs are there vs. the regular APs.
either way, even though it's heavy on local traffic (which makes weekends a not-so-good idea year-round), it's still a vacation destination for the western half of the US.
