RDP provides a comprehensive manual which includes step-by-step procedures. The manual was written by hospitality people for hospitality people and is not a typical “computer manual.” The guide includes tips on how to maximize profit by correct utilization of system features such as yield management, guest history mailings, and source of business reports. RDP’s Help guide is very easy to use. And, in conjunction with the online help system, RDP has one of the most complete documentation packages in the industry. The system includes a complete Help facility for each data entry field. When the operator does not understand a given prompt, online help can be accessed instantly in order to find an answer, without consulting written documentation.
