The financial reality of living such a life is saving hard between trips, which sometimes means actively cutting back socially. While a few nights in in exchange for a beach in Bali somehow feels doable, living on a shoestring also means inventive accommodation.

Parker house-shares with strangers, sets up beds in her car boot, stays in hostels, on sofas and in tents (setting up on a Spanish nudist beach one memorable week) and once slept in a converted ambulance for months. All of which would appeal to some, and be a nightmare for others.

It also means taking jobs when and where they come up. Having worked in bars, hostels, hotels, cleaning companies and nurseries, as a dental nurse and a teaching assistant, Parker’s CV means she can turn her hand to several types of work, and furthermore, usually with the kind of employers used to a high turnover of temporary staff – so flitting off for a few months with little notice rarely burns any bridges.

“I don't necessarily plan what I'm going to do, I take it all as it comes. I regularly live and work in Newquay – a lot of the jobs there are seasonal, though I’ve also made use of my teaching assistant qualification there on temporary contracts.

“I save up as much as I can and I’m lucky enough to be able to return to many of the jobs I've worked at.”
