Your weekly roundup of the hottest travel links across the net:

1. Want to travel the world for zero dollars a day? It sounds impossible but one man apparently did it and he recounts his adventures in a TV show that’s set to air in April.

This article from Forbes on the best travel rewards credit cards takes the work out of choosing a card.
