I wouldn't rush out and buy just for Disney trades. The agreement with RCI is only for two years, then Disney may renew or go back to II.
Maybe someone is confusing the past 10 year relationship with II that DVC just terminated.
I was told last week, by a senior DVC sale guide, that the RCI contract was for 2 years and that they really need to prove themselves for DVC to extend the contract.
I honestly can't see DVC signing a 10 year contract with RCI or II. There is not much incentive to commit for such a long period.
