Very patient and laid back. I cannot swim and was anxious to do this excursion. Chip and Sky made the experience worth it and made me feel like I didn't miss out, especially when I wanted to quit right from the beginning.
The package for pictures is a great deal. Chip took over a hundred shots and 25 videos which I'm glad because there would be no way to take your own.
The overall process from start to finish was smooth. Video, change into wetsuits, which is an experience all in it's own, and a very short ride to the dock. If you enjoy snorkeling, I definitely recommend this. We did the 8:15 am in January and water was a warm 68. It was warmer in the water than on land. I was, ironically, the only one not cold when we got out of the water. I'd recommend the heated boat.
