Leave the Safe Sea at home. I got the last of the Pica Pica the first of June and that was a remant that was hanging on a nasty looking mooring buoy line I new better than to touch on a safety stop (scuba diving) but I did anyway.

Those guys are gone. Look at the main page of the board under goods & services under diving and check a few of the dive operators home pages. Some have pricing for snorkelers to Turneffe or you could e-mail them. Pretty sure Amigos Del Mar does.
