I've been there, once at River Village II and once at Ridge Top Summit. RT Summit was nice and new then. RV II was worn down, but that was a long time ago, so maybe it's been renovated since. Neither of the units was anything great (RT Summit was better, of course), but they were large and spacious and comfortable. Last time we stayed was just at the time Wyndham was taking over the resort, so that's years ago now.
Shawnee has good activities, including a Saturday night karaoke party that attracts owners from all over the area, not just people who are staying there. If you have children, there are good arts and crafts activities for them. They also have scheduled times for board games, which we liked.
There's a big indoor pool and several outdoor pools. You can also use the pool at the Shawnee Inn, where there's a big hot tub, too.
The location is GREAT for the Poconos b/c you're near the Water Gap, the outlet shopping, Camelbeach, and anything else you probably want to go to. If you have young kids, the Shawnee water park, up the road from the Shawnee resort (I don't know if they're actually related--it's where the Shawnee skiing is in the winter) is small but fun for the young ones. They have magic shows and water-balloon games throughout the day.
Mind you, I haven't stayed at Shawnee in probably five years at least, but I hope there's something useful in here for you!
