Good info at the website
www.shawneeowners.com including a resort map. New units are Crestview.Have not stayed in these units as they are exclusively wyndham and not II participating, but I can answer about the resort and area. Resort is very spread out and car is needed. Rec center with small exercise room and large pool, gameroom,and minigolf. The resort does offer some activities including karaoke welcome party and NYC daytrip. In the resort complex is the Shawnee Inn and Golf Resort--beautiful 100 year old inn on the Delaware. Great history to the inn with lots of photos of the inn and past famous guests. Large veranda porch with rocking chairs overlooking the river. Timeshare guests may use the pool at the inn, but they must let you in and you need to bring your own towels. Also spa and golf course(seems very nice although I'm not a golfer) at the inn with discounts available for timeshare guests.
Restaurants on property include River Room in Inn-good, but slightly overpriced; and the Gem and Keystone brewpub--good food and beer variety. Both operate with farm to table concept with the inn growing their own vegetables and even has an apiary for fresh honey. Other closest restaurants are Saen Thai (great reviews, I thought was ok) and Inti Peruvian, which I loved and the General store for breakfasts.
3 very close grocery stores (within 15 mins on route 290)-the small Weis market,the larger Super foodtown and the brand new very large Price Chopper.
Things to do might depend on what you enjoy, but lots of outdoor things. Resort borders the Delaware Water gap National Recreation area and the Shawnee ski mountain is about 2-3 miles up the road. trolley tour nearby in the town of water gap is somewhat cheesy, but fun. Bushkill falls is about 20 minute drive and definitely worth it (both are about 10 dollars). In the summer you can rent kayaks, canoes or raft by the inn. Mount Airy casino is ~30 min drive. For shopping the Crossings outlet mall is about 20 mins away and on the weekends the Pocono Bazaar flea market is ~10 mins away and a blast.
Tried to cram alot into my reply; hope that its helpful. Let me know if you have any specific questions.
