Rates vary from inexpensive to hundreds of dollars per night. It really depends on what type of cabin and how large you are looking for. Volunteer Cabin Rentals has some one bedroom cabins starting at $99.95 per night (plus fees and taxes). If you want to go big and go luxurious, then Gatlinburg Falls has a 20 bedroom cabin that rents for up to $4000 in peak season, but it is worth it. On the other hand, Cabins USA has cabins in the $200-300 range and up.
Search several companies before making your final decision on your next vacation rental. You will be glad that you took the time to find just the right cabin that is in your budget.
