Every resort has its good and not so good. Best are actually the Epcot resorts, BW, YC/BC, Swan/Dolphin, simply because you can walk to two different parks from them, Epcot and MGM (you can also boat to either); but then they bus and partially share busses to MK and AK which is OK but not great. Likewise Cont and Poly have easy access to MK by monorail (can also walk to from Cont) and to monorail that goes to Epcot and monorail tends to be quick trip. But then they bus to other two parks and share with other resort or otherwise make stop which is OK but not great. The Epcot and MK monorail resorts are considered best for location. AKL has bus to all parks--good to all but still longer than if you could just walk (like at the Epcot resorts) or take monorail (like at MK resorts). WL has boat to MK (about 15 to 20 minutes) and bus everyhwere else (and shares with other resorts to MGM and AK), bus transpotation is OK, but of the resorts you mention it is probably the weakest link in overall transportation. Note, for going to places other than theme parks, like waterparks, downtown disney, or another resort (that is not within walking or monorail distance), most of the resorts are comparable and the transportation is generally mediocre and particularly bad for going to another resort.
