Tennis is free to play at the resort (there's a $20 cash deposit required). The courts are easy to find right behind the water sports shed (which is handy as that's where you get your racquets).

The deposit covers as many raquets etc as you need for the family so you only need to give $20 down for everyone.

You can book days ahead at the water sports shed if you're the type that likes to plan out your holiday!
