We stayed in building one. We came down the elevator, turned left, and came out the side door. We jaywalked (I know, I'm bad, but there was always very little traffic and it was quite safe) across Manchester right there and then walked up to the stoplight to cross to the West side of Harbor. Then you walk down past the entrance where the delivery trucks enter (and there's a sign that says "no pedestrians) so we kept walking past the bus stop. Next to the bus stop is the walkway, it cuts through the hedge, leading onto the second traffic circle. You are across the entrance driveway from everybody else who crossed by BWPPI. You can follow up your walkway around the opposite side of the circle, but while we were there, the north security tables were never open, so we frequently jaywalked again across the shuttle driveway, over to where everybody else was heading for the southernmost security tables.
