As I indicated earlier, our group experience has been limited to A&K and Travcoa. We have used A&K for more remote areas (India, Southeast Asia, Africa, Amazon etc.) and Travcoa for more "civilized" regions ( China, Italy, Danube etc.). The group size ranged fro 5 to 16. In terms of food, Travcoa allows clients to dine wherever they wish - room service, hotel dining room, or outside restaurant. There were some exclusions (caviar, Foie Gras). The major negative in group touring is the unavoidable regimentation and schedules. The obvious plus is not having to deal with most of the hassle and execution of complex itineraries.
