The cabin is in the smoky mountain area.
I have noticed, a number of cabin rental companies in the area all have the same clause, word for word, in their agreements. That kinda rules out going with a different cabin.
We just recently returned from the smokies. I do not believe the rental company from which we rented has a policy concerning firearms. The checkout information said to make sure you do not leave your firearm behind. We've stayed at a couple different cabins/cottages with this company and always have had great service and accommodations. They have some non cookie-cutter style cabins/cottages which actually have some character. Good luck with your trip.
