Check out Groupon. I got a family of four pass for $80 (basically one kid was free).
The cost of the tickets for adults are $ 31.94 and kids 3-12 are $25.55. I had a voucher that I used to go. There's many different places you can get coupons or discounted rates for most places in Pigeon Forge, Sevierville, and Gatlinburg.
