if you hit up gatlinburg cabins are prolly a bit more expensive... idk for sure though... but it's a smaller tourist place.. buncha shops.. sky lift, place to ski or snowboard... the drive is gorgeous up there...

pigeon forge has more to do though.. outlet malls for the misses.. go karts/ arcades for the guys...

i'm sure you can get a nice cabin in either city.. and they are maybe 15-20 minutes from each other so you can hit them both up in the same trip...
