I think most
DVC members who rent points do this. If yours doesn't offer, I'd sure ask for this info. You should be able to
independently verify the ressie. There is no reason for you not to have that ability -- unless the person renting the points just doesn't know what they are doing.
If you haven't already, go to the Rent/Trade board and read both the
FAQ and
"A Word to the Wise." Both contain very good info, and will answer a lot of your questions.
