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.
We always dreamed that the client could be able to get all optional extras in a few clicks. That was not possible until MMK introduced the XML service, which enabled us to get all info about current discounts and availability.
I appreciate Booking Manager as our primary system. It helps us to work easier and get real time worldwide availability. Furthermore, I appreciate their nice friendly team and efficiency. If every booking system could be so performant, I would be really happy.
