An itinerary is a plan for a trip or vacation. It is essentially a timeline of events and activities with additional notes, contacts, and other vital information. These helpful documents are used to anticipate and plan out any potential issues that may arise, as well as make sure that travelers stay on track and follow their predetermined plans. An itinerary typically includes details such as flight numbers, hotel bookings, travel times, reservation numbers, car rental details, and so on. They also contain information such as sightseeing options, restaurants to dine in, and activities to participate in. This helps travelers enjoy their trip more as they already have everything important planned.
