If you're coming from the WL, I'd say head out to the boat dock and hop on either the MK boat or the WL/CR/FW boat ... whatever arrives 1st. You can then hop the monorail from CR > GF, or MK > GF
The DTD bus normally stops at GF after WL (unless it fills up.)I am pretty sure that a bus goes to GF before going to a park from the WL. The person at the concierge desk here says no. Am I remembering wrong?
