Many people prefer traveling alone. Unfortunately, the solo traveler is often forced to pay a premium price for the privilege of sleeping alone. On package vacations, single travelers are often hit with a "single supplement" to the base price. To avoid it, you can agree to room with other single travelers on the trip, or you can find a compatible roommate before you go from one of the many roommate locator agencies.
GAP Adventures (tel. 800/708-7761 in North America, or 44/870-999-0144 in the United Kingdom; www.gapadventures.com) is an adventure-tour company with a good range of regular and varied tours in Ecuador. As a policy, they do not charge a single supplement and will try to pair a single traveler with a compatible roommate.
