that was my first time to Okinawa and snorkeling as well. the boys and girls are very nice and hospitable. even after course, sent us to where we are going to.
regarding to course itself, it's also amazing. our children liked snorkeling very much and the boat type is very safe and suitable for little child.
Only here, thank you for your participation in the course.
