We went to Pigeon Forge/Gatlnburg last June for the first time and loved it. We would like to go back sometime. We have a 10 year old daughter, and she enjoyed it.
We did things probably a little more budget than most. We stayed at a Super 8 the week before "peak season" and it was only $29 a night with a coupon we found locally. The place was newer and clean, and it had continental breakfast, pool, and hot tub. It was fine for a family of three who likes to spend money on other things, if possible.
We did Cades Cove and Roaring Fork. They were both great, but the trail we saw the bear on was Roaring Fork. Both have old cabins along the route and you can purchase little booklets that tell about the people who lived there at the visitor's center. These are under a dollar each.
We did two days at Dollywood. We were there at rope drop both days and left around three each day. It was pretty warm when we left. We have a season pass to Silver Dollar City attractions, so our tickets were free last year. (This year, I believe they only offer half-price.) Be sure to ride the trolley if it works out economically for you. Parking is $7 at Dollywood, but you can ride the trolley for 50 cents a person both ways from the transfer station where you can park for free.
We also did the Splash Country waterpark for a half day. Again, we rode the trolley.
We went to the Ripley's aquarium. We liked it a lot. We rode the trolley from Pigeon Forge to Gatlinburg so we wouldn't have to find a parking place once we were there. We also walked around Gatlinburg that day. It's fun just to browse up and down the sidewalks.
We spent an afternoon at Ober Gatlinburg. We rode a ski-lift up a mountain. My daughter and husband had never been on a ski-lift. This is also where the apline racer thing is. They also have ice-skating inside a mall.
Our room had a fridge and a microwave, so sometimes we ate sandwiches and snacks in our room. We also grilled out twice--once in a city park near Gatlinburg and once in the picnic area near Cades Cove. We ate at the Old Mill resturant one night and the Great American Steak Buffet two nights. We liked both. We also ate two meals inside Dollywood. We had BBQ both times there.
Sorry if this is long, but we really had a good time. When we were planning the trip, we couldn't find a lot of info. We did stay the first night at a place we had read about, but it was $60 a night for an older room that was not in its best form. We checked out there and found the place we did stay at the next morning. There are lots of cabin rentals in the area. We were the most active in the mornings and evenings. We often went back to the motel in the afternoon to cool off, and this was in June.
Have a great trip!
