Several posters have commented on how much easier it is to get ressies at OKW--which is true. One even made a rather snide comment about "that says something in itself." Just so you understand, there is nothing wrong with OKW!!! The reason it is easier to get ressies at OKW is because OKW is much bigger than BWV--there are many more units--so of course, your chances of getting a room there go up. OKW is a wonderful
DVC resort!!!! Frankly, we own at OKW and BWV and our family prefers OKW. The one and two bedroom units are much bigger there. We almost always vacation as a group of 8 adults, and we have more than enough room in a two-bedroom at OKW. We would never dream of having 8 adults stay in the BWV two-bedroom--at least not for more than a night or two.
The best advice I can give you--which others have mentioned--is to buy where you think you'd like to stay most of the time. Think of your particular family. Would they prefer more room, parking by the door and a more relaxing environment--or would they be happier in a smaller room but an excellent, very active environment.
Also, several people mentioned that the points for the standard rooms at BWV are not much higher than the rooms at OKW. Don't buy into BWV thinking that you will always stay in a standard room. Be aware, that there are more preferred rooms than standard ones and, from what I've read here on the Boards, freqently it is very difficult to get the standard rooms.
Both resorts are great!! We are so lucky that Disney tries to makes resorts which cater to the differing tastes of individuals. Since you'd have to buy points for either of these resorts on the resale market, maybe you'd be happier if you visited them first--looked inside the units at both places and see which appeals to you more. good luck!!
