Once in a Lifetime Vol. 2 presents a diverse range of unparalleled destinations for those longing for extraordinary travel experiences, whether they are seeking an adventure or a retreat. Some will be attracted to cities — the urban flair of Vienna, the bustle of Tokyo, the rich history of Istanbul and their sumptuous hotels. Others will want to be pampered at a wellness resort; find peace and quiet in an isolated mountain hut; fulfill a childhood dream of spending the night in a tree house; learn how to make wine; or see, hear, and smell a tropical rainforest.
