I would have bought sooner, too. We toured OKW in 1992, but I refused to even consider it until 1997, despite what DH said to convince me. I needed time to let it all sink in, I guess. So I bought 170 pts at BWV and had to add another 150 by the end of the year. I have 600 pts now, which is almost enough, but they are all at BWV, which I would not do again, since I only have the 11 month window at one resort.
I would have bought resale sooner. I really thought the process was much more difficult than it turned out to be, the Timeshare Store handled one sale, so I learned how it had to be done, and did the last one as a private sale.
I would have planned better, so that my contracts were at BWV, OKW, and either HH or Vero. I never thought I would need/want to stay in a grand villa, but I do, and a grand villa is too expensive at BWV compared to the other resorts.
