To me they are one and the same. It's not about obsessing but being informed about the membership and options. If one knows and feels the option isn't helpful for them, they can chose to ignore it, like walking DVC reservations for example. Unless one is willing to put a certain amount of planning, education and effort into the process; timesharing likely isn't a good choice for that person.All these tricks are overwhelming me. Yet I learn about them on TUG and feel the need to get the absolute best deal and use of my points. But what I really want is to enjoy vacations and not obsess over winning every time.
