Why not do something like Wizard Quest, but use Disney characters with a role playing story line similar to Kingdom Hearts.
It's kind of a theme park. Anyways, I loved the activities you could do there that were great family together experiences. I wished there would be a similar location in Florida.
Some activities at Stone Mountain...- a HUGE ropes course- pedal boats- petting zoo- a hands-on activities barn where you shoot each other with balls- hiking trails- simple train and boat rides.
PLUS! I had so much fun there, I didn't think of it later that these were all "healthy" fun, activities
I had an idea a while back that I posted to my blog invovlving an interactive 4D motion simulator, built around the characters Remy and Linguini from the Disney/Pixar Ratatouille movie. The premise is that you are Remy, and you're under Linguini's hat, pulling his hair to make him do the different motions required. It would take everybody on the ride, 4-6 people, working together to prepare a dish in the kitchen. Each person would have a pull cord similar to the ones used for Toy Story Mania and would have to pull it when instructed via voice or a special noise or an indicator light. There would be smells from the kitchen, heat, motions and other chefs yelling orders to you all while you're attempting to manuever Linguini to prepare the dish. At the end, once the dish is prepared, Skinner, the diminutive, tempermental Head Chef, would come over and taste your creation, giving you a surprised approval, or an angry disapproval ordering you to try again.
