I had been looking for a booking system for hotels and I purchased IceBooking. It is very easy to use and has a large scope in the front- and Backend. For users, the system is very easy to use and intuitive and has a good workflow. It also produces - and that was important to me as a web developer - a clear HTML code. The price performance ratio is excellent - 5 stars - great deal. Another 5 stars for the first-class support of the author.
