Are you looking for something to come in later in the evening and leave in the AM or something to come in and check out the area some?
If you are just doing a quick overnight you could do something like
this or
this that are closer to the exit off the interstate and would avoid
most of the major traffic.
If you wanted to come more towards Pigeon Forge area I would check out
River Plantation. It is a little farther off the interstate, and could get you into more traffic, but if you are looking to check out the Pigeon Forge area it makes a good "home base"
