Having been a rider (snowboarder) since 1986 back when only two resorts allowed us on the slopes, i have some experience in resort riding. I found Stowe to be fantastic, but a bit pricey if you don't have a pass or work there!
There are about 54 runs and the parking lot is directly at the base of both Mtns. The snowfall is pretty good as it is located on the biggest Mtn. in Vermont.
There are many backwoods trails, and trails only known by the locals or if you work there (which i did). So when you arrive, i suggest speaking with a parking attendant and asking them where "angel food" is if you want some good backwoods riding.
You can also hike up to the "chin" or other spots from the top of the gondola, if you want some real backcountry riding.
Also a good secret is "big spruce lift" located on Spruce Mtn. across the street. If you go to the top, and hike over the lake bed, you then have access to Smugglers Notch Ski Resort! Which is a whole other resort and they will allow you one run on your Stowe pass, or you can buy a day pass and ride over there if you'd like.
During peak you would be looking over $60 or $70.00 for a day pass, so your best bet would be to go on a off peak weekday, or to shell out and buy a season pass.
The food in the area (off the resort) is top notch, and again pricey.
I do recommend this resort if you have the money to do so!
