Solo travel produces specific psychological benefits — clarity, self-trust, presence. Travelling with chosen others produces different benefits — shared experiences, deepened friendships, different conversations than home permits. Both have place in adult life.
When group travel works particularly well
Old friends (university friends, longtime mates) where the relationship benefits from concentrated time. New experiences (cooking class, hiking trip, language immersion) where shared learning matters. Special occasions (milestone birthdays, weddings).
How to make it work
Choose travel companions carefully. Set expectations about pace and budget upfront. Build in some individual time within the trip. Pick destinations where you'll all enjoy the experience.
Mix solo and group travel across the year. Different benefits; both valuable.
