A lot of people are passionate about sports; same goes for travel. Combine the two, and you get what is believed to be the fastest growing segment in the travel industry: sports tourism, which is a $1.7 trillion business (Plunkett Research Group). It encompasses those who travel to a destination to:

• Watch a sporting event;
• Visit a sports attraction, such as a hall of fame;
• Participate in a sporting activity.

Campers now have a better offer if tents and lack of plumbing are not their thing. Airbnb recently partnered with the National Park Foundation to provide outdoor enthusiasts a new option to get outdoors, but still sleep inside. The new Airbnb accommodations will include travel trailers, tepees and mountain lodges in addition to more traditional housing such as homes or condos.
