I'd like to give a different perspective regarding 7 Springs. I skied there for the first time with my family last year from Dec 27-Jan 1. Our family includes the range from littlest boy who is afraid of some greens, intermediate boy and wife, very promising boy who will follow me nearly everywhere, and me who is a level 7-8 and lacks elegance in big moguls. We stayed in the big hotel at the base, in a "Tower Slopeside Family King" room. The crowds were not bad at all. Some lifts had lines, others didn't. The worst was the Polar Bear Express that takes you from the Front Face to the North Face -- I think I had to wait 20min one time. However, it's a lift you only take as transport to the other side, not really for skiing laps. Other lifts were 2-5min, and you could often just ski onto Avalanche and North Face chairs. I have had far more horrendous lift lines in Colorado and Tahoe. During Xmas week the lifts open 1 hour earlier (8am) so you can get in some good runs while the sleepy people are still abed. There is night skiing which I generally avoid.
The only thing that was annoyingly crowded was the main cafeteria at lunch, and one of the restaurants at dinner. At lunch it was less crowded in one of the restaurants adjoining the hotel, or at the Tahoe Lodge at the top of the mountain (or in your condo if you rent one). At dinner, the "Timbers" restaurant had a wait but the "Slopeside" never did and had a better buffet. There were also other eating establishments.
We bought a "Super 7" pass which allows 7 days of skiing in the season (not necessarily consecutive), and used 5 in December and the remaining two in February. The 7-day pass was less than the cost of 5 full-day lift tickets, so it was a good deal even though we weren't sure at the time that we'd be back later in the season. There was a free overnight ski check for hotel guests, so you don't need to lug your gear back to the room.
Considering the minuscule so-called mountains around here, I think that 7 Springs is one of the better ski areas near DC/Baltimore, and better in some respects than Snowshoe WV: it's much closer, and not nearly as windy. Snowshoe does have a little more challenging terrain, including the back slope, and it has the artificial village which is either better or worse depending on whether the 50mph wind is howling. Also, at Snowshoe the hot tub & sauna are open to all, whereas at 7 Springs they are reserved at additional charge. I think the 7 Springs hotel is substantially less expensive than the condo in the Snowshoe "Seneca" building that we usually rent.
