Resort Condominiums International, a timeshare exchange company. Acting as a broker between owners of weeks at approximately 3,700 resorts, RCI enables people to exchange their week for a week at a different resort for an exchange fee.

RCI was founded in 1974 by John and Christel DeHaan of Indianapolis, Indiana as a way for American timeshare owners to add flexibility to their ownership. RCI is currently a subsidiary of Cendant Corporation.
