Guidance promotion server, reservation support system, and non-transitory computer-readable medium storing program

A reservation support system comprising:

• a user interaction server;
• a guidance promotion server;
• and a plurality of service reservation servers, wherein
• a first service reservation server receives a request from a terminal via the user interaction server and the guidance promotion server,
• the first service reservation server answers a candidate group of a first service to the guidance promotion server,
• the guidance promotion server temporarily holds the candidate group of the first service, and also transmits a part of information constituting the candidate group of the first service to a second service reservation server from the guidance promotion server,
• a content related to description of a service content is provided from the second service reservation server to the user interaction server, and a candidate group answer of a second service is also transmitted from the second service reservation server to the guidance promotion server, based on the information,
• the guidance promotion server transmits, to the user interaction server, a narrowing result from a candidate group of the first service being narrowed from the candidate group answer of the first service, based on the candidate group answer of the second service, and the candidate group answer of the second service, and
• the user interaction server generates an interactive content related to candidate selection by combining the candidate group answer of the first service and the candidate group answer of the second service with a content from the second service reservation server, and transmits the generated content to the terminal.

A non-transitory computer-readable medium storing a program causing a computer to execute:

• a first step of instructing a guidance promotion server to receive a request from a terminal, and transmit the request to a first service reservation server;
• a second step of instructing the guidance promotion server to temporarily hold a candidate group of a first service being answered by the first service reservation server, based on the request from the terminal, and transmit a part of information constituting the candidate group of the first service to a second service reservation server;
• and
• a third step of instructing the guidance promotion server to receive a candidate group answer of a second service from the second service reservation server, based on the information, and transmit, to a user interaction server, a narrowing result from a candidate group of the first service being narrowed from the temporarily held candidate group answer of the first service, based on the candidate group answer of the second service, and the candidate group answer of the second service.
