Fort Wilderness was a wonderful stay for us (caterpillars dropping on our heads throughout aside! Even waiting for the bus, many folks got onto covered in them), but holy smokes so expensive as is anything Disney.
Kissimmee whether RVing or renting a house in the 80's, 90's and early 2000's served us well as a great baselocation to access many attractions and POI's. Cypress Gardens, Disney Theme Parks, Busche Gardens, Sea World, Universal, Gatorland zoo, outlet malls etc. We used to enjoy an evening walk to the "back then" several themed mini golfs in Kissimmee itself.
Tropical palms as mentioned above.
