Whenever we visit Pigeon Forge, we stay at Eagles Nest on rte 321 on the south edge of town. This park is a Passport America park and you can stay for a week at half price. The drawback is they do not accept credit cards for PA, but then again, most all PA parks don't either. Visit
www.campsave50percent.com to see their site. If you want to sign up, I'll send you my membership number as I get $10 off my next renewal for referring a new member.
There are also 3 other parks listed in Pigeon Forge, we just keep using the same one.
