The document is a Visual Basic program for a hotel reservation system. It allows users to enter a guest name, select a room type and number, and pick check-in and check-out dates. It then calculates the room rate, number of nights stayed, and any applicable discounts (0-75% off for long stays). The total payment due is displayed along with a record of the reservation added to several list boxes.
