AK, you can ski the park all winter with your friends, but when do you get the chance to ski 45 degree, 3,000 vertical foot faces for a week? you'd be lonely, but you could tell all your friends about it after haha.
i think it really depends who you're going to AK with, some friends of mine done a 10day ak trip and said it was one of the biggest anti climaxes ever, didn't live up to their expectations at all ...
