WL does not share a bus with CR. I believe that WL shares its bus with the GF and Poly. When we stayed at WL in 12/99, the ferry ran between CR, FW, and MK. You could take the bus to WDW, hop on the monorail and head to CR. But, if the ferry is still running the loop it was in '99, I would think that would be your quickest way to CR. Someone correct me if I'm wrong here!
