I used to have DVC in Old Key West but had to sell after a divorce
When I sold I had to sign a gagillion legal papers, so I think it is pretty safe.
I know you get all the same benefits / privilages. You own the DVC, just like anyone else.
I know you can start small and add points. I believe that they can be from different resorts, but keeping them in the same resort/month will make it easier for reservation planning I think.
I can pm you w/ the company I used, I'm not sure if I'm allowed to "advertise" it here. I can say they were very efficient, my place sold 2 days after listing.
I loved DVC/OKW...if I ever hit it big on a contest or fall into some primo paying job it's the first splurge I'd go for! Have fun & good luck.
Another thing to consider if you will be buying resale. Go for a WDW visit if you can and tour all of them to see what you like best.
