I'll chime in and agree with the above posters...you're home resort should be where you will feel the most comfortable.
That said, I'll pass along my personal booking experience this year...
Called MS in February to book a the last week in April. WL, OKW AND BWV were all available. Went with OKW because we were bringing guests. For our tastes, we love OKW when we bring along guests.
Also in February, I booked the second week in December. I had the option of BWV Preferred view, or OKW. Went with OKW because we don't like to part with those extra points, and I always seem to get a pool view instead of a boardwalk view. I went on the waitlist for BWV standard view. Within 2 months, my waitlist at BWV, standard view was granted.
You will see lots of posts of late with folks getting their wait list wishes granted for BWV and VWL...Why? Because folks who had ressies here have switched over to BCV's to give them a try. I'm sure the same thing will happen a few years from now when BCV's are sold out and they announce the openning of the "Villa's at Down Town Disney" (The current Disney Institute building site)
If you like to plan in advance, and the 11 month window is important (which it is VERY important if you like to vacation during peak travel times) then you do really need to consider purchasing where you would like to vacation the most. However, as others have stated before me, if you don't make your plans until the 7 month, or later mark anyway..than it really doesn't matter, as all resorts are up for grabs at that point.
We own at OKW and BWV..we like both resorts, however for US, we get that true vacation feel from OKW. We love the resort, spacious units and the relaxed atmosphere. We do enjoy BWV, can't beat the location, and when checking out the food and wine festival, there's nothing like being able to "walk" back to your room after a few samples!! The beauty of
DVC it they've built a variety of resorts to satisify all of our vacation styles...you've just got to make that difficult decision of picking which one will make you and your family the happiest!
Good luck!
