What's the difference between a court booking and an invite?

A court booking always involves the exclusive reservation of a court for you to use. You may have your opponent already organised or you may be inviting players to play you. You can also book a court without any invitation to others to play you - maybe you want a practice session.

An invite is an invitation to other players to play you at a certain time. It does not have to include the reservation of a court. It's the time which is important, the court you play on is relatively unimportant, though you may have a preference which you can set up.

An invite is slightly less likely to get filled because while you are waiting for an opponent to accept your invite, all courts may have become booked. But the flip side is that you can invite as many court slots as you like. This caters for the situation where players are free to play over a wider time period - for example any time in the morning, afternoon or evening.

If you do not have any flexibility in the time you play then booking a court makes sense. But you can only do that a limited number of times. If you are more flexible then you can issue dozens of invitations for all the times you're prepared to play.
