This. Southern vermont will be mobbed by fancy pants Manhattaners on holiday weeks. They ruin everything. J/k. OP: Killington is the better mountain between it and Okemo. Okemo is a better skiing mountain. Lots of flats and traverses make it not so much fun on a board.
Still think OP is better off at a smaller mountain at her level. Sugarbush. The whole right side of Lincoln Peak will be fairly empty and better for people who'll just lap the greens.
Sugarbush is a SMALLER mountain? Since when? It's one of the larger ones, and looks pretty intimidating when you first drive up. Mt. Ellen is smaller, but then he'll have to ride the smaller mountain to stay with his girl. A Lincoln Peak ticket is good at Mt. Ellen, but not the other way around. Plus it is a long way up there, with very little nearby. That said, there is a Best Western right off exit ramp that has a nice heated indoor pool, hot tub and private saunas with their own bathrooms (wink wink nudge nudge). Free breakfast, fireplace in the lobby, bar. Usually pretty cheap, but probably not on that particular weekend.
The other upside to that Best Western is that it is right between Sugarbush, Bolton Valley and Stowe (about 1/2 an hour from any of them). If you go to Stowe, it will be crowded as all get-out and wicked expensive, but there are tons of small inns and motels along the road in. The Innsbruck is one of our favorites...very old school, but free home-cooked breakfast, free soup and cider in the afternoon, a small bar, and two hot tubs, one inside and one outside. It's pretty cheap, and one of the closest inns to the Mt. Mansfield/Stowe.
BTW, we were at Okemo for Presidents Day a few years ago. Some friends have a house nearby, and we went just because we had cheap tix and it was close. That day they set their record for the largest crowds ever. Ever. Up 11% from the previous record. It was HELL. Half and hour minimum lift lines. Death on the slopes. Look for a more obscure mountain like Burke -- the farther north the better. But not much.
I forgot to mention, the Innsbruck has a chalet (two, actually), but not sure if it is worth it for two people. Sleeps about eight, probably too spendy...unless you're into spendy. Try Kayak...they'll show you everything available.
