Yes, outside the gate. You exit the buses, you would head left to go to the DHS front gate(you would also go this direction from the buses, but then turn right toward the dock before the main gate IF you were taking the boats). But for the walkway, when you get off the bus, I stead of heading left toward DHS, you would go right, directly off the buses. The walkway is right along the water, and it should be nice and "cool" that early in the morning.
I am attempting to attach a screenshot of the map from the WDW app. This is my first time ever uploading a file to the DISboards, so hopefully it works.
