We are using Booking Manager now for five years and it has made our work much easier. The program is good in general for running the business and having it all at one place, reachable from wherever you might be at the moment.
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.
