It is a violation of RCI's Terms and Conditions of Membership (Section 8) to rent, sell, barter, or auction, a deposited week or confirmed exchange, even if a Guest Certificate is purchased. Violation of this guideline could result in the termination of your RCI membership.
You may give a vacation to a friend or family member via the RCI Guest Certificate; however, you may not receive any compensation beyond the price of the exchange and Guest Certificate fees. Compensation includes anything of value, even another exchange vacation.
