The Near HH buildings are 11 to 14 and 23 to 26, with other neaby buildings used as overflow if there is a problem with the "official" buildings or if a bldg goes down for rehab.
Bldgs 11 to 14 will be just across the parking are for the check-in area, restaurants and main pool. That bus stop is the last to load before the bus leaves for the theme parks.
Bldgs 23 to 26 are a short walk across a bridge. Those buildings are at the first bust stop as the bus enters OKW, and first to load. There are 5 stops throughout the resort. It is only a short walk to the main pool, check-in and restaurant area.
