If you are ready to exchange your week or found a good rental, please select a Resort Location.  You can then contact the timeshare owner and ask if they are willing to rent their week or exchange with you, finally when the owner gives you the reservation confirmation from the resort we recommend you to pay with PayPal (they offer a very good protection guarantee)  There is no cost to contact anyone listed throughout the website.  But you will need to be a timeshare owner in order to exchange.

Keep in mind that there are a lot of users listed under "Multiple Locations" and they are able to book on several locations.
