It depends on what you want out of your spring break - skiing, skiing, and more skiing, or do you want to have some fun at night and maybe some ok shopping.
I definately would recommend a trip out west b/c of all the snow, but if Mom & Dad won't spring for it, here are my recommendations...
1.) Sugarloaf, ME - ok, so I'm originally from Maine and this is my all time favorite mountain so I'm a little biased but Sugarloaf has great skiing and it usually lasts through March. The downside is that the nightlife is not very good. But if all you want is a burger, a beer, and maybe a band til 8 then Sugarloaf is your place because The Bag rocks. They have the best burgers in the world!
2.) Tremblant, Canada - While I hated Tremblant because I went January and -30F at the base without the windchill was not my idea of fun, I can see it's potential. The skiing is good if you are a beginner to intermediate. The mountain is flat in the middle so if skating uphill in the middle of a diamond isn't your idea of fun - don't go there. But they have a cute village with good food and shopping. The condos are amazing - lots of fun for staying in and playing drinking games. And you can always spend a night or two in Montreal (an 1 1/2 away). Montreal during spring break is nuts! It's definately a long drive though - but if you're with friends - it's part of the aventure!
3.) If you want nightlife and crowded slopes - go to Killington. Hey, if you don't get hangovers you can beat the crowds by skiing early, then nap when everyone else wakes up. Big plus - Killington is probably the shortest drive for you. But the way this winter is going, March conditions may suck.
Good luck and have fun!
