It is useful to group Facilities to make bookings easier. In particular, grouping allows you to do the following:
Organise facilities so that they appear together regardless of their name
Book any available facility in the group without having to check to see which one is free
For example you might use a Facility Group if you had several squash courts that you hire out and want to check their availability. Alternatively if you had a number of classrooms with varying names, setting up a group called Classrooms would ensure that they all appeared together in the facilities list.
