I don't know how many Worldmark owners own in other systems, but I own many different timeshares, and Worldmark availability for peak-season reservations is shockingly bad. One of my timeshares floats almost 1-52 (it's something like 7-48), and is on the Southern California coast, adjacent to a state beach. One year, some owners got into a fist-fight at the resort over July 4th reservations. But, that problem is only for July 4th week. If I give the resort a choice of two summer weeks other than July 4th, I *always* get one of those weeks. Worldmark is way worse.
None of my other resorts are as hard to book as Worldmark. My 1-52 float in Scottsdale -- I have to be online when reservations open, but if I am, I can get one of the best eight weeks of the year. Summer in a week that floats from February to November in Myrtle Beach -- fine, and I usually see July 4th availability. I just booked New Year's Eve at Disney's Boardwalk, in one of the most desirable room types. No problem.
With Worldmark, there are resorts where I get online right at the 13 month mark, and everything is already gone. Until I read this thread, I had no idea how people even booked those reservations.
Don't get me wrong, I'm happy with Worldmark. But, that's because I get good value when depositing non-Worldmark weeks via Exchange Plus, and also because I can rent out my credits if I can't book them. When I joined Worldmark, I was truly shocked at how bad peak-season availability is. I live in Michigan, so I don't do midweek stays out west. I can't reliably get the sorts of WM reservations that are worth traveling 2,000 miles to use. If Worldmark didn't make it easy to rent out surplus credits, I'd probably sell. (Although I lucked out and Worldmark Austin opened at just the perfect time to get a bunch of rooms for my nephew's graduation -- and the resort is right next to UT-Austin!)
About my "Midwest" comment, I think the location of resorts is a factor, but not the main factor. And, I was really thinking about the differences between resorts in states that have an ocean coast and those that are in the overall middle part of the country. Arizona isn't "Midwest" in the usual sense, but it doesn't have a coast. And, I grew up in the Poconos, and they might as well be in the Midwest -- they are similar in geography to where I live in Michigan, but even lower in tourist demand.

And if credit availability is the driver, why not manage it by reducing the number of credits a member can control by doing away with the ability to have up to four years of credits in a account?
I wasn't thinking about the total number of credits available at one time, but rather the small difference between peak season/large units and off season/small units.
Mgearenters controlling many credits at once is certainly a problem, but I was thinking more of regular owners, not megarenters, competing for prime reservations.
FWIW, I find DVC to be a flawed point system. Their point values have created too great a draw for studio stays while disfavoring the 1BR units....
There is a flaw with the Disney one-bedroom points values, but it isn't because of their size. It's because the one-bedrooms only provide onsite Disney privileges to four people, which is the same number as the studios. Yet, the one-bedrooms cost about twice as much as the studios. (I'm not sure the Disney resorts that aren't affiliated with theme parks have as much of a problem with the one-bedrooms being slow to book up.)
This four-person occupancy limit for one-bedrooms is a mistake that Disney made in designing their early resorts, and the Declarations don't allow them to re-allocate points to fix it. The newer resorts improve on this problem by having five (or maybe sometimes six?) people allowed in a one-bedroom. Plus, the newest Disney resort, Riveria, has some studios that are for just two people.
Overall, though, the problem with slow bookings for one-bedrooms at some Disney resorts supports the idea that point/credit allocation must truly reflect the use one can get out of a particular size (and season). There can't just be an arbitrary allocation of credits/points, which seems to be the case with a lot of Worldmark resorts.
On the topic of megarenters (who I think are part of the problem, but not as bad as the credit allocation problem), what about the idea of limiting the total number of guest certificates an owner can have per year? I know some megarenters are actually managers for other owners. Still, would it be possible to have a rule that one person/company could only have a certain number of GCs per year, even if they were managing for other owners? This would be hard to enforce, but just the threat of investigating and maybe canceling reservations would probably make a lot of owners think twice bout giving their points to a megarenter to manage. The question is whether there is the legal standing for such a rule. Eric, what do you think?
