This week on the Peter Greenberg Worldwide Radio Show, we broadcast from the Moon Palace Golf & Spa Resort in Cancun, Mexico, perhaps the largest hotel in Latin America. We’ll be joined by Arnie Weissmann, Editor-in-Chief ofTravel Weekly, who discusses the changing definitions of volunteer vacations, and how over half of the traveling community gives back while on a leisure trip"as well as how this is transforming some travel brands.

Plus…have you ever traveled around the world to pursue one particular passion? Art history? Music? Fishing? Evan Saunders stops by to explain his worldwide travel in pursuit of the perfect…club sandwich! His report might surprise you. There’s all of this and more when the Peter Greenberg Worldwide Radio Show broadcasts from the Moon Palace Golf & Spa Resort in Cancun, Mexico.
