Solo travel intentions are on the rise in the U.S. and particularly with millennials. In an MMGY Global Survey of 2,300 U.S. adults in July, 37% of millennial respondents they indicated they intend to take at least one overnight leisure trip alone during the next six months. That's up 5% from a year ago and 8% from two years ago, a much sharper rise than older generations. Some 25% of all respondents said they'll take at least one trip by themselves before the end of the year, up only slightly from last year and their willingness to travel unconventionally marries this uptick.
