I kinda hafta stay here in NE. I'm bound by college schedule constraints, a wife who only just started skiing this season (I have her up to handling anything groomed regardless of pitch), and equipment.
The only way I could even consider going west is if somebody out there could guarantee me a pair of long straight skis to use. I'm not trusting the airlines with my precious gear, and I cannot and will not use shaped or "fat" skis of any kind. I don't care how deep the snow is, or how big the mountains are.
Some suggestions have been made above as far as deals (stowe???). Stowe, Sugarbush, Killington, etc... would be bad places for such a gathering. You need a big mountain with a variety of terrain, LOW PRICES and no crowds. Saddleback, Sugarloaf, Burke Mountain, Jay Peak, Smuggler's Notch, etc... would all be better locations. Killington is frighteningly crowded and a rather unfriendly place to ski, especially to have lessons. Sugarbush has awesome skiing but is rather expensive, and has a poor lift layout (and always has lifts on wind hold). Stowe is hands down way too expensive for most people, even with a large group it would be difficult to get the cost down, and it's not as big an area as it seems. After a week at the one area, most Bears would be bored stiff unless they hiked to the summit (a good long 800 vertical foot walk). It's also not well suited to teaching in groups because the best terrain is often quite narrow (or closed).
Jay Peak is well layed out, is big enough that Bears can discover as many new things terrain wise on their last day as they did on their first, has a good terrain balance for Bears of all levels, offers INCREDIBLE group discounts for skiing and lodging, is within driving distance off points as far south as Philadelphia (7 hours), and as far northwest as Ottowa (4 hours? I may be way off). Jay also within one week will have fresh snow (75% chance of a dump), and hardpack, which whether you love it or hate it is always good for the learning process. And it is one of the few places in the east with honest god above treeline skiing (along with Sugarloaf, Saddleback, Cannon and Whiteface), and actual short couloirs (along with Whiteface and some out of bounds at cannon or stowe) as much as 1000' long ("the pumphouse").
Think about it this way. The folks who would go to an eastern academy are the folks who WOULD go west, but can't. The best thing to do is recreate a western environment for the occasion, with the best of the east thrown in as well. To that end there are only 5 areas that would qualify: Cannon, Jay Peak, Saddleback, Sugarloaf and Whiteface. Cannon and Whiteface should be ignored because the snow can be scarce, and when it is scarce they groom the piss out of everything.
This leaves three options for the best possible academy experience in the east, while maintaining a low cost and snowy, crowd-free experience (essential to the learning process).
Jay Peak - 2,153 vertical feet (2,201' with hike up to summit), 75 trails chutes and glades(plus 6 unmarked couloirs), 1 tram, 4 quads, 1 triple, 1 T-bar, 351" annually (306" this season), Catholic Mass on sundays, best feature SNOWFALL
Saddleback - 1,875 vertical feet (2,168' with a short above treeline scramble which also accesses a back bowl with 800' of vert), 48 trails (plus over 1,200 acres of open and gladed forest), 2 chairs, 3 T-bars (all very fast and wind protected), 200" at lodge (2,400') and 302" at summit (4,124') best feature NO WIND HOLDS
Sugarloaf - 2,890 vertical feet (3,002' with hike to summit), 129 trails and glades (1,410 acres inclusive boundary to boundary), 4 quads, 1 triple, 8 doubles, 1 T-bar, 1 handle tow, 180" at base, 250" at summit, best feature SIZE
