As a former sports journalist and content creator, I swapped the press box for a permanent desk several years ago. Since giving match reports the red card, I have enjoyed developing my writing and research skills in a few other areas, and now I spend my time doing something I really enjoy - sharing the best ways to save on travel with our wonderful readers.

I love nothing more than exploring different parts of the world and learning about new cultures (and taking in the occasional sporting fixture, if at all possible). I’m just as happy on a quick city break in Lisbon as I am navigating my way across the width of America, and firmly believe everyone should have the opportunity to enjoy travelling regardless of their budget.
