Minybear,
If you like BWV's & you want to stay there most of the time, you need to buy there... BW is very difficult to get into certain times of the year & you would do better having your 11 month booking period there...
The good news for you, is that the resale prices on the BWV's has come down quite a bit, and it's quite possible for you to get a contract priced between 58 & 62.00/point... You will have to pay closing costs of 400.00, but split that with the seller if they'll agree to it....
Also, BW has two sets of views, the standard views look out over the front of the resort where you pull up & they also look out over the tennis courts as well.... those views are significantly less points than a preferred view... But they are hard to book, because there's not all that many...
If you want two vacations per year, I would seriously think you'd need 250 points... Go to the points calculator here at the Dis & put in two likely sets of dates & see what you come up with... Keep in mind, cutting off just one weekend night can save you 40+ points, so you could always cut one vacation a day short to save money... We have 250 points & we stay 12 nights in a 1 bedroom standard view in the low season.... This year though we are going for 10 nights in November, which requires a bit more points...
Just follow the link above to visit The Timeshare Store website, they are highly regarded among the board members here....
