The LTA guidelines permit organised activities for larger groups including coaching and club sessions. Given that, the club schedule is unchanged. Also the club tournament continues.
However ad-hoc social play is limited to groups of six. It is not immediately obvious, when looking at the booking sheet, whether a court is booked by a singles pair or a doubles foursome. We must avoid the situation where both courts are playing doubles at the same time. Hence, whilst this rule applies, singles are asked to book court two in preference. If both courts are free book, court two. Then a doubles group knows that they can have court 1. Likewise doubles groups are asked not to book court 2 at any time.
