As an owner of nine timeshares, I have had the unique ability to use many of the exchange companies over the years. In my opinion, the best customer service is offered by VRIety Exchange (powered by Trading Places), the best value is offered by VRIety Exhange and the best exchange company overall would be a tie between Interval International and VRIety Exchange. RedWeek is up-and-coming and if they are able to increase their inventory, their low cost and fair points-based system may overtake the others. Having the diversity of four exchange companies makes vacationing anywhere possible. Our road-trip this summer will include one II short-stay, one RCI trade, and one VRIety split-week trade in addition to hotel/extended-stay reservations. The diversity of memberships has offered options, but I do not plan to renew my RCI membership when it expires next year because of their drive to sell deposited units to travel agents; an exchange company should be in the business of exchanging units not selling then to outsiders.
