We are coming to Pigeon Forge area the 1st week in April. We will be staying in a cabin for 4 nights. We have 2 girls age 10 and 1 boy age 9. What are some activities not to be missed? One of the girls wants to go to the Titanic Museum. The other 2 want to see the Lumberjack show. They have talked about ziplining. My husband would love to go white water rafting. We are planning on walking around in the Smokey Mnt park. Any other suggestions. Thanks for the help!
