Ever wanted to ask someone a question about their job, but it never seemed appropriate? Now's your chance on Ask Me Anything with Today FM's Dermot & Dave.
On this morning's show, Mark jetted in (well he walked actually) to tell us all about life as a travel agent.
As always, the listeners had plenty of questions as they asked him things like - His top tips when booking a trip/travelling? What lesser known locations are the best gems? If you're splashing out on a luxury trip - where's best to go, and what's the most popular? Does he know any loopholes into getting a cheaper trip? And more.
He was up to the challenge and answered everything without taking a break (he's sick of breaks)...
