When traveling alone, I often feel petrified by all the newness and all the changes in routine. However, traveling with others helps only by making me mask the whole time. The same fear is still there; I just stuff it down for the sake of seeming normal to my companion. Even so, once the trip is over, the emotional fallout for traveling with someone is worse for me than when I travel alone. Consider your level of independence and the needs of the trip when making this decision.
