Forget most of what you know about II when dealing with
DVC. DVC is the member and as such you have no fees except the $75 exchange fee. You do mostly request first up to 2 years out. That's the good news. The bad is that DVC tells you which resorts you can exchange to (only about 10 % of II), no getaway rentals, bacially can't trade up in unit size, can't call II directly and no bonus weeks. If exchanging is at all important to you, I'd suggest you consider other options to complement DVC. Of course you can always to direct exchanges or use one of the independent exchange companies.
