Pros: Close to NJ/NY, Variety of terrain, friendly people, Great snow
Cons: can get crowded, need to work on after hour amenities
I have been going to Mt. Snow for almost 10 years and the new ownership has really improved the mountain a lot. They have put in over 10 million or something like that into snow making and groomers. There is another lift or two ready (6-pack to the top is the rumor) to go up this summer and looking down the road there is more to come.
Now to the Mountain
There is a great variety of terrain, from easy trails like ridge and snow dance to ripcord which has one of the steepest in VT. There is plenty of glades if you know where to look (they took them off the trail map)(the glades on north face and sun brook are really fun and the glades between trails at Carinthia are a little more open, also fun) and there are moguls all over the place (hit up bear trap for some fun) they also seed moguls on Roller coaster. Then there are a large number of wide groomed trails that make for great wide open carving (my favorites are exhibition on the main face and free fall on the north face). For those who like to throw down some tricks (I personally don't) two years ago or so they made Carinthia an all park face (only in the east) with 8 parks, 2 pipes (most features in the east). Although it took away some fun terrain it moved all of the boarders and trick skiers away from other parts of the mountain and has attracted a lot of new riders.
The few cons are it can be crowded on busy weekends and holidays and one the slopes shut down there is not much to do on the mountain but the valley is killer with tons of stuff to do and plenty of restaurants (just does not have the "Ski Village" many like on the mountain). Also the lift tickets (like every VT mountain) are fairly expensive.
**UPDATE: The have installed the 6-pack bubble to the summit for this year. They also improved the base area with the tap room open after the slope closes and added a burger joint with some killer burgers. The mountain continues to get better and better. Also while it can get crowded at the base there are plenty of ways to avoid the crowds (just stay off the bubble and that the "exposed" high speed quad (horrible i know) to the top).
