CCV is pretty expensive at $220 per point. And because a lot of those points are from cabins, it makes studios hard to get the whole year. Of course, if that's what you really want --studios at CCV -- then home ownership there makes a lot of sense.
AKV and Riviera may be the best "value." Riviera at $195 per point, and lower with incentives. Considering you get another 49 years with it too. AKV is $176 per point, about the same as Riviera with incentives, but only 37 more years, which is still a lot of time. And as mentioned, home ownership at AKV gives you access to "value studios" and concierge rooms, which are almost impossible to book at 7 months.
OKW and SSR are the cheapest, but they are less desirable for a reason, and the contracts are a little shorter. (Both significantly shorter than CCV and AKV, OKW being the same as AKV, SSR being a few years shorter).
Now, arguably... the best "value" is something like Hilton Head or Vero Beach -- much cheaper. But if you're comfortable with some of those couples weekends at those resorts, and others booked at the 7 month mark, it can be a great value.
