What is there to do in that area? I know there's Dollywood, but I don't know what else... our Disney trips (without paying for one child who's still under 3) are around $1600 before airfare/driving costs, so that's similar - maybe we should look into it?
Depending on your choice of accomodations, food and entertainment...a week can cost quite a bit at Gatlinburg/Pigeon Forge area! I could not stay there an entire week for under 2K. Gatlinburg is one of the most expensive places to visit if you do all the road side attractions that cost $150 a pop for 2 hours of entertainment. I really feel that Disney is just as affordable if you can swing a discount.
I live 2 hours away from Gatlinburg and we go there often and although it costs quite a bit...we do visit at least once a year for a 3 or more night stay, usually renting a cabin. I easily drop 1200.00 on a 3 day weekend and that is w/ no shopping (we don't do shopping) and taking in what nature offers rather than hitting road side attractions.
Dollywood has a great theme park, water park and is as clean as Disney and unique in it's own way. There is more to do than I can name...river tubing, white water rafting, of course the Smoky Mtns, hiking, driving tours, Cades Cove, Ober Gatlinburg (season skiing), chair lifts, shopping galore, Wonder Works, Dinner Shows, Magic Shows, Nascar Go Carts, mini-golf, Ripley's haunted house, Ripley's aquarium (very nice), etc.
Most of all it is also absolutely beautiful in the fall.
We like it because the Smoky Mtn national park is awesome and we like nature... but it is totally different for us than a vacation at Disney World and it is not cheap. For entertainment, it's more like vacationing and hitting attractions in Orlando rather than visiting Disney World unless you do the "nature" thing. Myrtle Beach is much cheaper than Gatlinburg for a week.
