I've never been to Killing ton before, my college kids really want to go there. I would like to hear any experiences of actually staying at those condos. Can you get back and forth to the rest of the mountain easily?
I've never stayed in Sunrise Village, but I think you would enjoy it. I have stayed in condos near the main Killington base and along Rt4 over by Skyeship base. Sunrise beats both of those for ski-in convenience and has a nicer "woodsy" feel. Killington is a big place, especially horizontally, so you'll always have some traveling to do to get from one side to the other, but returning to Sunrise from, say Killington Peak, can be done without any lift rides. If your college kids are aggressive skiers they will enjoy being close to Bear Mtn. Sunrise is also good if any in your group are very mellow skiers because there are a lot of LONG low-crowd green circle runs over there.
