The ease of use, as it is very intuitive. Also, because of the fact that it can be used by both employees and customers, it really helps keep everything updated and accurate. I have not found anything so far to dislike about this program or any features that could be improved upon. The software is easy to learn and has many useful functions for both booking agents and customers. It makes our life easier, all our employees are able to do their job without having to spend time searching through files manually for information.
