I have 3 kids and there will be a 4th on our trip with us, their ages are 5, 5, 3 and 8 months. We are staying in a cabin in Gatlinburg (May 28th- June 2nd) and are looking for things to do. We are thinking of Dollywood, Splash Country (weather permitting) and Wonderworks. Do these places have things for young kids (the 5 and 3 year olds)? Are there any other suggestions of things to do with young kids?
