OKW is our favourite resort - and yes, it is big - but most of Disney’s resorts are big. If you want to be close to the Hospitality House, main pool, clubhouse, restaurant and store, then the best buildings are 11, 12, 13, 14, (these are directly across from Hospitality House) 15, 16, 62. 63 and 64; (62 is probably the most sought after building, so chances of getting into it are slim). Even though it is large, the resort is very quiet and laid-back. The bus service is generally good. No matter where you are situated, a bus stop is only a short walk. The main bus stop is directly in front of Hospitality House. The only drawback with it is that it is the last bus stop to load, so buses might be crowded. It is also the last to unload, so you have to take a trip right around the resort before disboarding. The buildings to avoid are those on South Point Road - Buildings 47 through 54. They are the most remote. Our personal favourite is 45 or 46, situated on the banks of the Sassagoula. Very serene.
BTW - Olivia’s is one of the best “sleeper” restaurants at WDW.
