The most affordable way to play tennis in Swindon is at St Marks Recreation Ground. A key fob is simply a way to open the gate and find a court to play. Key fobs cost just £30 per household per annum - it's by far the best and most affordable way to play tennis with fellow fob holders. It comes with online court bookings a week in advance so you can make sure a court is available. Payment is made online via direct debit. Alternatively, you can register in person at St Marks where cash payment is accepted.
