I actually don't find people who travel all that interesting lol.
It's not just the act of travel. But that is an odd thing to say. Simply having access to a wider range of places, cultures, sports, foods, environments, etc., should put you in a place to experience more interesting things. Just the sheer variety of opportunities afforded you being in new places with new people on a constant basis should make you have some interesting life experiences. Obviously interesting is subjective.
What kind of person is interesting to you though? If you had the choice of a girl who never left her hometown vs one that has traveled the earth and you knew nothing else about them, you would guess who had more interesting stories to share with you?
