We use Booking Manager every day. I like the possibility of having the access to the system from my mobile phone, so even in the evening when I am with my friends I can check the best offers and create direct options or bookings.
XML gave us the possibility to work faster and well organized as well as to search for the most specific needs of individual client's wishes and programs that we offer.
Booking Manager is one of our favorite partners, as the API data structure and performance is very good. We especially value the personal contact to the developers and their open-mindedness for constant improvement.
