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 of Travel 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.

Also stopping by is The Los Angeles Times‘ Hugo Martin, who runs the numbers for us on airline ticket pricing and strategy, and how this is negatively impacting a growing number of small to medium-sized U.S. cities. 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.
