Oops. Ron is correct. I misunderstood the question. My earlier answer was regarding when you are depositing points to RCI. To answer the original question (if this is what you meant), if you have already deposited points into RCI and later use them to book an exchange, no reservation transactions from Wyndham will be used in the process of booking that exchange. RCI charges an exchange fee, though, at the time of booking. I believe the fee is $179 if done online and $199 if done through the call center.
Yes, that is exactly what I mean- I have long since deposited the points into RCI and paid the Wyndham fee so I was wondering if I would use a reservation transaction to book now that the points are in RCI and not Wyndham any longer. Thank you both for the replies.
