Amy, in addition to the above info I'll say that my views on what I own over the years (
DVC and otherwise) have evolved. I want good stuff, mostly at least reasonably close to DVC qualify, and I want it as cheaply as possibly. I've evolved from mostly owning to trade to owning to use and trading to supplement, for variety and for sport. The thrill of the chase so to speak. I do have high demand resorts weeks that I would only trade in a special situation (DVC, HH Marriott's), then I have a trading Marriott that is a lockoff, a single MX resort that works on points and a lot of BG points. This is very different than a few years ago. Currently I have 433 DVC points down from 885 a few years ago headed to likely 100 or less in 2-3 years. Previously I owned a different Marriott week to trade but feel that resort may be dropped from Marriott so I sold it and bought another. I owned several fixed weeks in Aruba but fees were going up and we've never been to Aruba to I converted them to BG. Over the years I've likely owned 30-40 weeks/contracts that I don't currently own. While I haven't learned much the hard way fortunately, I have moved closer and closer to the ideal situation for myself and my family.
I do searches in II daily for what DVC options show up no only with everything I own now but many of the options I no longer own still show up in my online II account. Then I play with all type of unit/resorts to see what will and will not pull the DVC units available. Will a 1 BR from a lower rated resort pull all DVC 1 BRs available? Will a studio pull a 1 BR? will a bonus week get it? do I have to use a higher demand/value week or resort to get what I want. What are my chances of getting a 2 BR? a 1 BR during a higher demand time like summer? Obviously this is not a perfect science and it relies on what's sitting in II online where ongoing searches have already picked over the inventory to the real answer is likely even better than the picture I get if I do ongoing searches. But I've assumed if I see it online consistently with a given option, my chances of getting that same thing or something similar the next few years with that option is very good. And it tells me if I can use a $200 option or need to use a $1000 options for example to get what I want.
