The price has steadily gone up in the last few years. Currently it is $43.50 plus tax for ages 12-59, children 4-11 are $32.35 and seniors ( 60+) are $40.15.
Be prepared for a lot of walking. The park is spread out, a lot of steep hills, so you walk up and down quite a bit, if you have any walking issues you might want to pay to rent a motorized chair. A lot of the demonstrations and shops are up the hill so wear good shoes with good tread (especially when the ground is wet, no flip flops, you'll have no traction). The leather shop is wonderful, the smell is worth going into the shop for. They have a clothing shop which has cute clothes but is expensive. There is a spiritual shop, a candle shop (which also has demonstrations and you can dip your own candle in colored wax), lil' dollys dresses which has cute dresses for girls which really isnt too high priced. If you have a little girl with you, go into that shop early in the day and ask them if they need a model. If they do not have one already your childs age they will fit her with a dress, socks, hair bows and any other accessories necessary for the look they are wanting to achieve and if your child wears the outfit for the better part of the day you are given the entire outfit. It is so others in the park can see how cute they look and to get them in the store to buy. There are many eating places on park too, a lot of booths with food and a few restaurants ($$$$$). Aunt Grannys is probably the best. It is an all you can eat buffet with good ol fashioned southern cooking. Some of the other food booths sell dippin dots (frozen dots of ice cream), cookies, pop corn, drinks (you can get a free glass of ice water if you ask the places that sell fountain drinks)frozen lemonade and vendors with carts that walk around selling bottled drinks. The shows are good and are included in your admission price unless they are special concerts which usually require advance tickets. You won't see Dolly here unless it happens to be one of the four times she comes to Dollywood a year. Kind of a let down, you go to DIsneyland expecting to see Mickey mouse and you do, so naturally you'd go to Dollywood expecting to see Dolly but you have a better chance of being in an airplane wreck than seeing her. It is worth going once to say you've been but to buy season tickets to me is a waste of money, it doesnt change enough to not get bored.
