my only plan when I buy is to use the purchase in all ways possible
Good to hear! I think that's exactly right. And, if you make a good decision about something with lots of high-value options, then disposing of it will also be relatively easy. For example, your converted VV week is probably an easy thing to get rid of. CWA is a little harder (it has higher than average fees on a per-point basis) but still very doable.
I think if I were buying specifically for II, there are two paths to take. One is to try to get a low-cost Marriott or a voluntary Starwood in the highest season at a place I'd be willing to visit at least some of the time. Those probably won't be free, but they will also give you at least some internal preference in II for some of the best (non-DVC) inventory there, and also should be sufficient to get DVC. The other is to buy an off-brand resort at a decent location in peak season--and I'd want it to at least be Select (silver) if not better. As
@rickandcindy23 mentioned here or maybe in another thread, something that isn't rated runs the risk of being shut out of all but the dregs in II. Remember to avoid any Orlando-area resorts, as if you own any you will be barred from exchanging in. From
the DVC/II Disclosure:
II does not issue Confirmations for (i) an exchange into any DVC Resort located in the Orlando/Kissimmee, Florida, area to any Interval Member who owns a week-specific interest in a Member Resort located within the Orlando/Kissimmee, Florida, area
(Note that that language is more strict than RCI Weeks used to implement. In RCI Weeks, you could *own* something in Weeks that was in Orlando, but as long as you didn't use that ownership in any way for the exchange, it was allowed. This seems to say that if you *own* any weeks in Orlando, you will be barred. They might end up implementing what RCI did, and I suspect anyone in a points program that has an underlying ownership in Orlando will be allowed.)
Before committing to either of these routes, I'd also want to see some of the sightings threads to see who could and couldn't see DVC. My II weeks used to be able to see them, and these are weeks that see most but not quite all of the high-quality II deposits. But, a lot might have changed in the past dozen or so years. The Marriott/Starwood route is probably safe and will have good exchange options in any event--again, as long as you avoid Orlando.
Will Club Wyndham/ developer Founder's Platinum trade with II still?
No one who isn't currently able to use II will be able to unless Wyndham changes the rules---and seeing as how Wyndham owns RCI, that's unlikely.
Each Wyndham account is affiliated with exactly one exchange company. Originally, the affiliation was determined by your
first Wyndham purchase in any account. There were a handful of resorts that,
if you bought them first, would affiliate the account with Interval, but most affiliated with RCI. If memory serves, some years ago Wyndnam told all owners with II-affiliations that they were being moved to RCI unless they explicitly opted out, with a very short deadline. (That's a fuzzy recollection, though--I wasn't affected so I only paid half attention). All new Club Wyndham accounts are now affiliated with RCI no matter what the first ownership is.
