Gary M, thanks for mentioning the change in the route at 3 PM. I was wondering how we managed to use the buses between WL and MK without having gone to FW.
We found the bus transportation fine at WL, though we enjoyed using the boat to the MK more. The smaller launch to the CR was rarely crowded, and was usually arriving just as we stepped onto the dock. We like walking around WDW (good thing, huh?), so we often took this launch between CR and WL and walked back/forth to the MK.
We used our car to get to Epcot several times, which saved time waiting for the bus but lost time looking for a parking space. We also took the WL/TTC bus several times to catch the monorail to Epcot, because I like how it streams through Future World before coming to a stop!
I'd just allow a bit more time when using the WL buses to reach my destination on time.
