When I bought my timeshare in Key West I didn't plan on exchanging. I knew that I wanted to be in Key West every year for our annual family fishing vacation. I purchased because I had trouble finding rentals that met my needs and my budget. Now it is set up every year and the cost of ownership is very low compared to the high priced rentals in the area, if you can find one. For me, owning locks in my yearly vacation at a fixed price and gurantees me I'll be were I want to be! No exchange company can do that every year and the price surely goes up for rentals.
