I was on the WL for one day in a GV at OKW in December. I did not really think I would get it, but it came through last week!
I think you have a chance at BWV, but as the previous poster said, you would have a better chance if your WL was shorter. Could you separate it into two WLs? That might help.
I cant believe your family did not want to stay in a GV. I am really looking forward to our stay in one.
Enjoy your trip.
