I have bought the tickets and will be bringing my 18-year-old son with me. We land in Cebu July 18 and will spend four nights there then take a ferry to Duma. I have reserved two rooms at OK Pension House, you never know when I might meet a new friend, for four nights. After that, I want to take him snorkeling somewhere close and economical. I hope you all might steer us to a nice place where he can swim to without using a boat, please.
