George, I owned various multiple floating Weeks for more than ten years. They worked great for me, back then. Last year I bought WorldMark, (essentially a Points ownership, but with no underlying deeded resort), and I've since sold my remaining Weeks ownership. My biggest reason to go only with WM was because of how I travel now.
It used to be a timeshare trip was a destination vacation, and I'd book two Weeks worth of vacation back to back. It reduced the cost of airfare and such. I found over time that I didn't always want to spend that much time in that one location, but I was locked in. A Week is still a week long, which is one of the best things about owning a Weeks timeshare. But once you've used that week, you have nothing until the next time that Week's usage rolls around. The only way to get more predictable travel time, (not by renting or a Last Call thing or whatever), was to buy more Weeks someplace. That can get to be pretty expensive.
With WorldMark, (and any similar Points ownership), short stays are possible. I can book a night or two or three, and the associated expense is minimal. (There's a housekeeping fee, but it's assessed on all stays, regardless of length.). If I want multiple short stays in a given year, I can do that. I'll have five WM vacations under my belt by the time next year. I couldn't do that with a Weeks ownership.
The other side of the coin is that if I want to stay longer than a week someplace, I can do that, too. The system gives me flexibility, and right now that's a good fit for how I travel. As they say, "your mileage may vary."
