I've lived in Branson for ages, and there were rumors for a long time about a certain big chunk of land being bought by Disney, but nothing ever seemed to happen! I would love for them to put a park here, but I can't imagine them getting much business in the winter! Everything in Branson shuts down Jan & Feb (All the shows, theme parks, etc).
Maybe somewhere in southern TX? Warm, somewhat near the ocean, and still centrally located!
