If you want to party and be close to the lifts, stay at vail village. Or stay at Breckenridge.
I would also reccomend going to Whistler. It is amazing
Jackson Hole is also a good choice.
Looks like you have some of the major destination resorts included here.
How many days are you going to be boarding? the epic pass might not be worth it. If you get the regular 3-4 day pass for vail, you can also ride beaver creek and breck...or any combo of those
