Our group of 6 adults booked a private tour with IDC in February 2023 to visit North Vietnam and Phu Quoc Island. One thing that makes IDC different from other travel agencies is the prompt and courteous response from Alex and his staff. We always got a text or phone back within the next hours. Our requests for accommodation in Sapa, Yen Tu, and Hanoi were difficult, but IDC did it without a glitch. The arrangements for car, guide, driver, restaurant suggestions and domestic air travel were perfect and satisfied our demands. We had used several travel agencies in Vietnam in previous trips, but we could say that IDC surpasses our expectations. We can recommend IDC without hesitation.
