A flashpacker

A flashpacker shares some of the characteristics of a backpacker: a sense of independence, no fixed itinerary and relatively long periods of travel to more exotic and far-flung destinations. Whereas backpacking is traditionally associated with budget travel and destinations that are relatively cheap, flashpacking has an association of more disposable income while traveling and has been defined simply as backpacking with a bigger budget.
