Prince Harry
15 of 16
How he travels: After some bad press for a hard partying Las Vegas vacation two summers ago, Prince Harry went a completely different route late last year. He joined 12 other crew members on a 140-mile charity trek across Antarctica.
Actors Alexander Skarsgård and Dominic West also joined the trip, which raised money for wounded warriors, called Walking with the Wounded South Pole Challenge. Grueling conditions and expensive gear means this trip can cost around $65,000.
