OKW is doable without a car, I have stayed at OKW both with and without a car, but it is much easier at OKW if you have a car. The resort alone is huge and if you are in a building in the back and are someone that will go to the store, restaurant, Community Hall, exercise room, main pool etc a lot, it is much easier to have a car just within the resort alone, and also because the only mode of transportation to anywhere but DTD from OKW is bus and while OKW is not located any further away than any of the moderate or value resorts or AKL are, it is still not right next door to a park, numerous restaurants etc, like all the other deluxe resorts are; bottom line it is much easier to have a car while at this resort. Also you can self park in front of your villa in the parking lots that are located in front of almost every building and when you use your car a lot and there is no valet service this is a BIGGIE.
