Thanks for the replies. How is it that DVC is able to limit their resale buyers from using RCI but you all seem to suggest that as long as the resort I am looking at participates with Interval, I can deposit my week even when purchased resale? I also wonder if the resort can say that resale purchases would not include facility access for owners year round and limit your access to only when staying on property (like DVC).
I don't even know how one can obtain this information since the developer may not be so forthcoming with these answers.
Unlike most resorts / systems DVC is not under the control of owners it is in the sole control of DVC. It was written that way and thus you are bound to it. That includes their absolute right to limit the "owners" rights to use the exchange system of their choice. They MUST use whatever DVC says they will use as all inventory assignment is handled by DVC.
In most other systems, even if the property is RTU type, you still hold some type of guaranteed use rights or an actual deed. With those base rights you can, assuming the resort was at one time affiliated either RCI or II and now no longer officially supports that, choose independently to place YOUR absolute use rights with II or RCI (or SFX or whoever) despite any protest from management.
Avoiding systems where such high level of inventory control exists (DVC) and other owner negative issues (developer/management holds all the control, including Board seats, ROFR clauses in resales, etc) are all part of the due diligence required of a buyer as they decide where / what makes a good value to own.
Best values tend to be smaller, owner controlled resorts in high demand areas. Once you get to medium to large sizes it often makes far more sense to rent what you need rather than owning. The shear quantity of inventory they tend to flood the market with tends to hold rentals near the annual fee mark with the premium not even close to the high cost of actual purchase. Plus with rentals you have far more control over the use dates/unit size / view etc as you can demand that the owner give you what you want or you look to another. They are stuck with what they can get for their ownership and have no real fallback option but to lower the price asked (and use that to your BEST advantage).
What you CANNOT do is trade for an II week (or RCI) then RENT that week. You have no right to do that under the trade rules.
