The use case diagram for hotel booking demonstrates the different tasks of the hotel booking system. The primary actor is the guest, who can act by looking for hotels, booking them, and going to and from them. There are some other actors like a receptionist that aid in changing bookings; then at the end, we have the payment gateway which performs all payment transactions. The hotel manager supervises everything. This diagram reflects the movement of motions within the system, meaning how users engage with hotel booking systems.
