If possible, take along your own mask and snorkel. It's nice to not be restricted by the CTI rules and go to snorkel when you wish - at any time during the day. (watch the water ski boat!) With you own equipment you can be assured of a great fit - which means no struggling with leaky masks, snorkels, etc. and it is much more hygienic! Now is a great time to purchase your gear - end of summer - everything is going on sale!
