Hi, Jenn -
We're also BWV owners who plan to try out Vero. We're going for 3 nights at the end of November. Don't have any experience to comment on your chances for July 2002, but I do have a suggestion for you to consider since your trip is still more than 1 year away.
How about "trading" BWV points for Vero points? I've seen posts over on the rent/trade board related to this. If you can find someone, you'll both have the advantage of the 11 month booking window. Maybe this won't work for you, but since so many of you are going thought it was worth mentioning. Maybe you could even book one of the Grand Villas!
Whatever happens, wishing you a wonderful vacation.
