No amenities at the hotels change except for convenience of quick access to both Epcot and DHS. Convenience is a large component of "location, location, location."Why would it effect any of these hotels? Yes one of the reason you pay is for the location but the location of these hotels isn't changing. You will still be able to walk to 2 parks. Not one amenity will change due to the Gondolas
In the real estate market, when convenience of a location diminishes, prices fall. Anyone who thinks that will happen at WDW, I've got a time share to sell you...
