Camelback or Shawnee are the most-used in the area. Blue Mountain and Big Boulder are other options, but I'm not at all sure of their offerings.
Camelback is bigger than Shawnee and is in Tannersville.
Shawnee is near the Delaware River.
Both are nice ski resorts.
Group of 10 ... Girl Scouts hmm... rules out the brew pubs.... there are plenty of chain restaurants around. There's a nice buffet-style Chinese restaurant called East Gourmet right at the Bartonsville exit of Route 80, in the Giant shopping plaza. About $12 pp, not including a drink, and the food is quite good and varied. Depending on when you go, though, you could have a bit of wait - it gets packed at prime dining time (e.g.: 6 - 8). There's Texas Roadhouse in the Stroud Mall, kind of a BBQ/steak chain ... but there's peanuts everywhere, if there are any allergies in your group (free bucket of peanuts of every table).
Red Robin and Lonestar Steakhouse are near the Bartonsville exit also. Near Shawnee, not a lot that could seat 10 with ease and would suit a Girl Scout group. There's a Mexican restaurant in the Wal-Mart plaza, Mo's, that has great burritos. Wal-Mart plaza is the "East Stroudsburg" exit off Route 80.
