All good suggestions.
We use a private cabin owned by a friend of ours. Great couple, clean cabin, not on a crowded "cabin rental" property, and priced well. It's a 2 br, wrap around porch, hot tub, master br jacuzzi in the bathroom (2 bathrooms total), sat tv, wood burning fireplace, great kitchen/dining area, and again...private.
I can get the info from the folks if you would like. Prices are comparable to your standard hotel rates or better and you're essentially in your own mountain home. Has a stellar view of Mt. LeConte (which I HIGHLY recommend hiking). Also, you MUST grab a steak at the Smoky Mtn. Brewery.
Here's a pic of the outside when we went a couple years back.
