Educational and cultural institutions have the opportunity to bring an added dimension to group travel through the supplemental content provide by academic expertise. Alumni travel with their school for both the additional information and the social bond of traveling with friends. An institution can also build community by offering specialized trips for purposes such as service, singing, donor cultivation, or cultural appreciation. Yet, most institutions do not have the expertise or resources to plan alumni trips so they turn to operators specializing in affinity travel. Many of the operators serving the affinity/educational travel market will also plan trips for groups and might offer trips directly to travelers interested in group travel.
