I love BWV and even though we are not in the market to add more points, I would still buy BWV today if I were. (That's assuming it would still work out to be less expensive than paying Disney discounted cash stays and assuming annual passes are still available to purchase. This last is a very important factor in any purchase decision we would make).
The BW location cannot be beat - transportation options are arguably the best on property, and the point chart cannot be beat. Once the refurb (scheduled for 2023), the rooms will be among the nicest in
DVC.
I would rather be where I want to be for the next 19-20 years than somewhere else for the next 40 -50, wishing I were at the BWV. We do not want to leave a financial obligation to our daughter and she really isn't the fans we are, anyway.
Since we never expected to sell our contract, anything we may get when/if we sell is gravy. We are fortunate in that we were able to buy with discretionary funds. It won't change our lifestyle at all if we cannot recoup any of the initial purchase price.
As nice as the Riviera is, I would not buy there due to the transportation. The skyliner just cannot be counted on as a reliable mean of transportation. Staying at the BWV gives us easy access to it, anyway - we used it just last week to get to Topolinos, and often choose it to return to the BWV from DHS when we just want to enjoy the ride.
I still believe that in most cases, you should buy where you want to stay. Any savings are soon forgotten when you are staying elsewhere, wishing you were somewhere else.
