To customize a tour, we have to include the following information in a client form: Contact information: This should include the client's name, email address, and phone number. Travel dates: The client should specify the dates they would like to travel. Group size: The client should indicate the total number of people in their group, including any children. Travel preferences: The client should specify their interests and preferences, such as the types of activities they enjoy, the style of accommodation they prefer, and any specific destinations they would like to visit. Budget: The client should provide an estimated budget for the trip, which will help you tailor the tour to their financial constraints. Special requests: The client should indicate any special requests or needs they may have, such as dietary restrictions, mobility issues, or other accommodations. Emergency contact: The client should provide the contact information for a person to reach in case of an emergency. By gathering this information, we can create a customized tour that meets the client's specific needs and interests.
