What is the Best Ski Resort to stay at in New England?

My boyfriend, another couple and i are planning on going away over New Years Eve. We want to stay at a ski resort and be able to ski. We are two young couples and would like to have things around us to go do. We were thinking of Loon in NH but not reconsidering. Are there any suggestions on what mountain and resort and if there are things to go close by. Thank You!
