We stayed there twice, but not in the cabins. The main building rooms are large and have huge balconies overlooking the lake and mountains. A mini fridge comes with the room. Definitely do the meal plan, it is very reasonable for what you get and the food is excellent.
The kids entertainment is quite good, the lounge acts vary in quality. We got to see Elvis and he wasn't too bad, but Kenny Rogers kept forgetting the words to Ruby.
We enjoy going to Clarks Trained Bears and Franconia State Park while staying there. The paddle boats are fun, too. There is an outdoor pool with a hottub and an indoor pool, also with a hottub.
The pools are clean and heated.
If we're lucky we'll get to do a couple of days there this summer. Have a great trip.
