Pigeon Forge/Gatlinburg is a hopping place in general and has 20 credits available for enthusiasts.  Check out these:

Rowdy Bear Gatlingburg

Most of these except Dollywood are open pretty late each night so much can get done in a couple of days.  It certainly is a pricey place though.  Getting all these credits will run in the $200-$300 range.  Good luck on your trip.  Now that we have done all these places, glad to answer any questions yu might have.
