The best thing I like about this software its simplicity of use as well it's user friendly interface which allows you not only book hotels but also manage your reservations in one place so that there isn't any confusion or chaos when managing multiple properties at once! One downside i dislike with rezbookers was their customer service team could be more responsive though they are very professional otherwise everything else has been great! So far we haven’t had problems using RezBooker since our first day until now (we have used them over 10 times). We solved many issues by creating an account through RezBokar such as making changes after check-in/check out etc., Also made cancellations easier especially if something comes up during travel time or late hours where someone doesn't answer calls / emails ect..
