You can either walk over the bridge to the main hub and get the first stop in front of the store (South Depot) or you can get the bus stop on the road next to the parking area by the buildings (East Depot). It will really depend on which building you are in as to which is more convenient. We liked the walk over the bridge and being the first on the bus. We were in Oak in the courtyard facing the parking lot. It was only a few minutes walk to the South Depot.
There are only a four buildings in Bayou considered preferred and having stayed there I wouldn't book 14 or 15. I don't want to be that close to the food court, pizza delivery trucks and all the other vehicles that enter the back of the food court via behind these buildings. We think 16 and 17 are best of all worlds, close to food court/main hub, quiet pool and our car. But do love 27 that overlooks the river, mill etc.
