I have heard they are expecting between 1 and 2 mill a year. Not sure about that.
The 500 acres is family land. I do not own but could use. Probably would not want to put any permanent structures there but had thought about the camping.
The theme parks will have condos for guest to stay in. I think they will try to keep guest in the parks and provide most everything, food, shopping, golf etc from within the park. I would think the guest may travel form one location to the other park( about 2-3 miles apart).
Keep the ideas coming. This could get very interesting. There is a local church that is starting a construction project that will run into the Millions.
