If there is a pathway from CR to WL then it involves either a bridge or a tunnel and as far as I know neither exists. There is a wide waterway between the two resorts. There is a boat that runs continously from CR, WL and FW and it takes all of about 3-4 minutes from WL to CR.
You are correct though with respect to the getting to the monorail, as we have done it many times while staying at WL. Hop on the boat and within 10 minutes you can be at the monorail station and off to Epcot or MK.
