Disney does own some random apt complexes and land that just isnt obvious. Including where that Dennys is on the corner. Move one over and youll see dolphin cove (disney doesnt own that) but move 1 more over, Disney DOES own those. Quite a few of those places have "month to month" leases. So disney actually highers an outside vending company to run them until they finally decide what to do.
If the city does own Garden Walk, i think its only a matter of time before disney will scoop it up. Obviously the planning has stalled, and develpers have been arguing over it since 2003. Giving to disney would be wise. A full fledged 3rd park (in maybe 10 years) would be a great great great boon to the city.
