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.
Online booking feature makes everything so much easier for the customers, they can do everything themselves!
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.
