Is it possible to display a table:
Down the left is the list of services (in my case rooms for hire) and calendar to the right.
This means that instead of checking EVERY dropdown list of Service/Room, it is visually on the one page so you can see all the services/rooms and when they are booked.
It is a helicopter view about it all that is missing.
It would be good to have it output on a separate page or where ever you want to put it.
