Resale benifit loss?

We were discussing a purchase with a sales person at a Cobo time share that their price was to high. When we brought up buying a resale he ranted on that 3rd party resale owners don't get the same benefits as the original owner. IE, if we bought a even year time share we could not accelerate another even year forward into a odd year as we can when we buy from the resort. Anyone have experience like this?

That is true.
