Leisure & entertainment attraction information is available from commercial attraction-provider servers. Users subscribe to a computerized service to facilitate making arrangements for visiting such attractions. Subscribers fill in wish-lists to specify their level of interest in specific attractions, in getting together with specific other subscribers, and in arranging their preferred schedules for outings. An encounter generator processes the subscriber wish-lists to identify matches of subscribers who are interested in the same attraction, who favor each other's company, and who are free at the same time. The system notifies the matched subscribers, optionally offering ticketing and/or reservation assistance. The system is adaptable for serving singles who wish to identify and get to know a prospective mate through mutual visits to attractions, as well as individuals, couples, and families who want to go out with their existing friends or make new friends.
