check ebay as well. sometimes you can get something cheap elsewhere and then trade for a week in aruba. we have traded for 3 weeks the past 2 years with little or no trouble. there are two companies that trade timeshares: II interval international and RCI resorts condominiums international. we use II. watch you maintainance fees though.

www.redweek.com also has rental info on all the timeshares
