Bookings are not instantaneous, you need to make your booking more than 15 minutes before you want to start.
Courts 3 & 5 are en-tout-cas. You must water these courts before play. You must bag these courts when finished by dragging the bagger from the net to the fence on both sides to remove footprints and ball marks.
The correct tennis shoes must be worn on these courts. Soles of the shoes must be flat with soft edges. Herringbone pattern is the best sole to provide good grip on en-tout-cas courts. Shoe soles must not have a raised pattern.
