Which of the following is essential to do before finalizing an itinerary?

Before finalizing an itinerary, confirming transportation and accommodations is a crucial step in the planning process. This ensures that all aspects of the travel experience, such as flights, trains, or rental cars, as well as hotels or other lodging, are secured and aligned with the client's travel needs and preferences. Confirming these details helps to avoid any last-minute surprises and guarantees that the client has a seamless travel experience.

Additionally, having these confirmations in place allows for a more accurate projection of costs, travel logistics, and the overall itinerary structure. It also provides the opportunity to address any potential issues, such as availability or changes in schedules, before the trip is booked and finalized. Ensuring that transportation and accommodations are confirmed is pivotal in building trust with clients, showing that their travel advisor is methodical and detail-oriented in their planning efforts.
