Got our money's worth
Yes, the cabin was old and the carpet was stained in a few places, but the linens were washed and fresh and the owners were very nice. The king-sized bed was very uncomfortable.
We did not eat in the restaurant - we were told the cabin had a kitchenette. No oven though, so we didn't get biscuits the next day. We tried on the grill but that didn't work. Also very lacking in pots, pans, plates, silverware, so I hope they like what we donated.
The "petting zoo" consists of two rabbits, a turtle, some budgies and a couple of finches. Our daughter (11) enjoyed that, but the water for the animals look like it hadn't been changed in weeks.
The fireworks were great on Saturday night. The pool was cloudy, so we didn't let the kids spend too much time in there and made sure they were showered later.
There is no lake access from this lodge. I didn't know Lake Whitney only has one beach, but we were within a 10-minute drive of it.
Would I go back? Probably on another Groupon, but not at the prices they list on the website.
