Great choice!!!and great time to go, usually. Should be plenty of snow on the slopes. I suggest you stay in the Village. I have done samae on numerous occassions and always enjoyed it...but it can get windy...after all you are on top of one of the highest peaks in WV and the MidAtlantic. Kids will especially enjoy eating at the Pizza Restaurant and the ambience of The Junction restaurant (lots of parts from logging trains, pictures of same, etc.) helps entertain them. If you are there in mid-March then the tubing and slopes at the Silvercreek area will also be open. If you stay at Allegheny Springs, there is an outdoor pool and hottub associated wtih this Lodge as well as using the Split Rocks pool complex just next door. There are all sorts of specials in March, so be sure to inquire. Some weeks the lift tickets are free, most of March the lodging and tickets are reduced. Be sure to inquire about packages...for example...I am staying at Allegheny Springs this weekend and early next week in a studio (room for a friendly 4 with bed and couch) but the cost of lift tickets for the four days for two packaged with the room is less than $100 more than the cost of the room without any tickets. This year there is something new call the BIG TOP which is near the Shaver Center at the Village and has all sorts of fun thing for the kids and family to do. If you are lucky and get a snowstorm while there you can snowshoe, go for a horse drawn sleigh ride, etc. Frankly, underground parding is not that big a deal to me, since you can park at the lot at Allegheny Spring, even use valet parking, and if you are not going to need the car what difference does it make. By the way, frequently all the undercover parking at Rimfire is full and you have to part outside anyway.
And lastly, the newest lodging in the Village, Expedition Station just opened and I think it is a lettle less expensive than the other Village lodges. And I guess that you have surmised that the Village is a walking pedestrian mall. One nice thing about Allegheny Springs lodge is that it has check-in at the desk in the Lodge and you do not have to go elsewhere to check in, get Concierge services, front desk services, etc. And there is a wonderful huge room off the lobby with plenty of soft chairs, sofas, computer, etc. for all the guest to use. And there is a restaurant in the building, albeit a bit expensive. By the way, there is a 4 Star restaurant within walking distance of the Village - the RED FOX - that has unbelievable food and menu. You won't see it listed in Snowshoe materials as it is privately owned and operated.
I would also suggest you not stay at Silver Creek Lodge due to a lack of restaurants, etc. You can always ski and tube there, taking the on-mountain bus service from the Village.
If I can be of more help...give me a holler.
