What information should you have ready when contacting a Marriott property to make a reservation for a client?

When contacting a Marriott property to make a reservation for a client, having your IATA number ready is crucial as it identifies you as a travel agent. This number is recognized in the industry and often facilitates smoother communication and transactions with hotels. It can help in securing the best rates, obtaining reservations, and providing certain benefits exclusive to travel agents.

While knowing your client’s travel dates, the number of rooms required, and their preferences for amenities is indeed important for effectively making a reservation, it is the IATA number that legitimizes your inquiry and helps in the booking process.
