Sorrento offers timeshare properties at various locations around the world. Its web site states, "The concept of vacation ownership with Sorrento begins with the comforts of a 'home resort', a villa or condominium at any one of our extraordinary properties. You select the season and the one, two or more weeks you wish to vacation. Your home resort can be lushly tropical, sparkling with snow, nestled in the vibrant heart of a great city, at the edge of the vast Pacific, or lit by the warm Mediterranean light. You also have the opportunity to exchange within a worldwide system of world-class options. So you're free to visit new destinations or trade your week(s) for cruises, airline travel, or a wealth of options offering remarkable flexibility. Only a Fortune 500 company such as Sorrento could design, build and maintain an ever-expanding array of spectacular vacations, and every one of them is yours to enjoy with a priority exchange."
