What key piece of information should be included in a travel agency's terms of service?

Including clear cancellation policies in a travel agency's terms of service is essential because it sets expectations for both the agency and its clients. Clear cancellation policies inform customers about the conditions under which they can cancel their travel bookings and the potential financial implications of doing so, such as any fees that may apply or deadlines for cancellation. This transparency helps prevent misunderstandings and disputes, providing a level of assurance to clients and building trust in the agency.

While other options like marketing strategies, customer testimonials, and social media links may enhance the agency's presence and credibility, they do not directly address the legal and operational clarity required in a service agreement. Terms of service primarily need to focus on the operational aspects of the business relationship, such as cancellations, refunds, and other crucial policies that protect both the agency and its clients.
