I like its simplicity of integration, very easy to use even if you are not an expert of this software. Its user interface is quite simple that anyone can understand it easily. The best part about the ResEngine is that it’s so simple to integrate with your own website and CMS. It has never failed me in any way, and have always been able to provide the needed information as expected. Nothing too much bad to say, It's a good tool for our hotel management. We are able to track all the activities of our guests at different parts of their stay.
