The more links a node has, the more connected it is, and the more likely it is to function as a hub (Lohmann, Albers, Koch, & Pavlovich, 2009). Tourism destinations that adopt a position as an aviation hub or gateway, and that are well serviced by air connections and accessible to a wide range of markets, can play an important role in stimulating the development of local and regional economies (Box 14). International cruise ships can cany thousands of passengers from port to port.
