I'm not sure of the names of the roads but, follow the signs(once on Disney property)to Port Orlenes but stay in the left lane and go just PAST POR to the trafic light, at the light turn left. The HDDR parking will be on your right, but before you get to the main entrance to the campground. Once you have parked, walk to the bus depot(to the left of the kennel) and take any internal bus(orange, yellow or purple) to the Settlement stop, HDDR is just down the path from the bus stop. To get home, walk back the Settlement stop and again take any internal bus back to Outpost(if you take a different bus each way you will get a good overview of the campground.
