You can start by asking friends and family if they want to go with you on the trip. If you can't find a roommate, you can sign up for a double room, and indicate that you are looking for a roommate. The trip leader may attempt to assist in locating a roommate for you, but is not responsible for finding roommates for single travelers. The earlier you sign up the better! The trip leader will establish a cut off date where if no roommate is found, you will have to either pay the single supplement, if available, or cancel your participation in the trip.
