When I first went to WDW in '99, I thought it would be pretty much the only time I would go. Then, we traveled there, with another family, in '01. My dh went that time (ladies trip the first time...3 generations). He had an okay time, but wanted to go just as a family the next time. So, back we went in '03. Within 3 months we owned at BWV. Owning at BWV has changed our vacations at WDW a lot. We no longer feel the pressure to see it all, do it all each time. We know we're going back soon. We can bring friends with us...I am traveling with dd and another mom and her dd in Oct '06, the two girls will both turn 13 within days of each other, in WDW! It's wonderful to be able to bring others with us. We always feel like we're coming "Home"..hence the big 'Welcome Home' when you arrive.
We love DVC...it has allowed us to vacation in a place we normally wouldn't have thought of. It allows my type A dh to vacation with his dd, without getting bored and going back to the office...there is something new to do every single trip.
