Wow, so many different opinions. Of course a car would be the quickest. Other than that I'd say definitely the resort boat from WL to CR, and the monorail from there to GF. We have done if before. Here is why. One, it is a lot more fun than taking any combination of buses. Two, it is probably the quickest. The boat from WL to MK (can take as much as 30 min) and boat from MK to GF (up to another 20 minutes) could be long, depending on how long you have to wait for boats. The whole bus connection could be similarly long, depending on waits. The WL boat to the CR is a very short ride. The wait for that boat generally isn't any longer than the wait for the MK boat. The monorails run very regularly and would be a relatively short wait. If the monorail is running without delay the whole trip should be not longer than 30 minutes or so. Combine that with the fact that you get a boat ride, you get to walk through the CR, and you get a monorail ride. It is not only efficient, but fun.
