A lot of people email me with this worry, my only answer, don’t worry!  Imagine the excitement and energy of everyone in your tour on the first day, everyone wants to make new friends and have the trip of a lifetime, afterall lots of personal time, money, planning has been invested.  Typically, there is a large group of single people, and from day one they start eying each other.  Those who are already paired up or have signifigant others back home will find each other and naturally groups will form. Also, the first day you board your bus your tour manager will encourage everyone to find someone new to sit with.  If you’re on a long trip your tour manager will also encourage sitting with new people during the long bus rides.
