Just a quick question for the many Bonaire veterans on this site. We'll be returning for some shore diving and will be taking a family member along who will be snorkeling. They are not that experienced. Because of some of the entries being a little on the rocky side we requested that they get fins that would work with regular rubber soled booties. She has purchased "snorkel fins" with "socks"...Argh! I don't feel this is enough support . Am I wrong? Any thoughts. I've only been to Bonaire once before, but would like to hear the opinion of some of you veterans.
