What is one benefit to customers of using online booking tools?

One significant benefit of using online booking tools is the decreased wait times in line. When customers utilize these tools, they can efficiently reserve their desired service or product in advance without having to physically wait in a queue at a location. This streamlined process allows for better time management and enhances customer satisfaction, as users can quickly make arrangements at their convenience rather than spending time waiting for assistance.

While the other options touch on relevant aspects, they do not directly address the immediate customer experience related to booking efficiency and time savings. For instance, increased rental rates may not be seen as a benefit, and the availability of more cars does not necessarily relate to the booking process itself. Similarly, while less time spent on the phone is advantageous, it is not as directly impactful as the benefit of avoiding physical wait times altogether.
