If your son likes caves, there is one in the Panhandle before you get to Tallahassee. It's called Florida Caverns State Park in Marianna. HOWEVER, the Panhandle is still recovering from Hurricane Michael. Call first to see if the park is open. One of the few dry caves in Florida. Florida has the best state parks in the country (not an exaggeration, they win awards). Our son prefers state parks to Disney nonsense, thank goodness. Annual pass is MUCH cheaper, lol! We've only been to Disney once as a family and were not impressed. Unbelievably expensive.
