Although requests are never guaranteed, there are some great King Bed room locations. There are some in the Magnolia Bend mansion building that are absolutely prefect, they directly overlook the river and are right next to the bridge that leads via Ol' Man Island to the main building. There are also some King Bed rooms in buildings 14, 18 and 27 which are conveniently located, although most of them don't overlook the river. So rather than requesting just a building, I would suggest you request (by fax 3-5 days out) what you what - something like "convenient access to the main buildings, ideally building 85 directly overlooking the river (e.g. 8739, 8742, etc), or if those are not available buildings 14, 18 or 27".
