( CNN ) -- If there 's any truth in the old saw that London 's streets are paved with gold , it 's probably because they 've been gilded by cash stripped from the pockets of tourists .

Asia fields the majority of the list 's most affordable cities for a holiday . The list says an evening out and overnight stay in a four-star hotel in London will relieve visitors of $ 523 -- more than three times the cost of the same break in Hanoi , which is named as best value . Travelers to Paris should be warned against working up too much of thirst while pounding its boulevards -- the city is identified as the priciest place for pre-dinner cocktails .
