Make Travel Plans
Most 18 year olds haven’t really had the opportunity to travel much. Broaden their horizons by planning a trip together, or better yet, a trip for them and their friends (if you happen to be their parent). At this point in their lives they are ambitiously adventurous and eager to explore the world on their own. These experiences can be some of the most enriching of their lives, and a gift like this really puts everything else on this page to shame.
