Thanks for the info about the evening time on the island penny3333. I will share it with the group.
I have snorkeled in many parts of the Eastern and Western Caribbean and have a great respect for what is "out there" and our environment. I wasn't aware of the feeding portion of the snorkel until after it was booked and paid for by our company and can't say I agree 100% either however it should prove to be an interesting experience none the less.
Thank you for your input.
