The main transportaion difference between BWV & WLV is that when staying at BWV you can walk to Epcot & MGM or take a boat to either of these parks, plus you can walk or boat to Epcot and take monorail transport to MK. At BWV the only park you must take a bus/drive to is AK. At WLV you must take a bus/drive to AK & MGM, take a boat to MK, and you can either transfer to a monorail from MK to Epcot or take a bus to Epcot from WLV. Location wise, no doubt BWV is better. Also getting to DTD from WL takes longer due to it is farther away, But do not negate WLV, it is a wonderful resort with a totally different and much more quiet laid back atmosphere than BWV, it just takes longer to get around if you are using WDW transportation. But both are great resorts.
