A few options include: - Paradise: This word conveys a sense of a perfect and idyllic place, much like Xanadu. - Utopia: Similar to paradise, this word refers to an imagined place of perfection and happiness. - Eden: Often associated with the biblical garden of paradise, this word can suggest a mystical or utopian place. - Shangri-La: This term was popularized by the novel Lost Horizon and describes a mythical, remote haven of peace and contentment. - Nirvana: While commonly associated with Buddhist philosophy, this word can also be used to describe a transcendent state of perfect happiness and peace.
