Trying to decide which snorkle tour to take, the choices are Goeff's Caye,. Rendezvous Caye, or Sergeant's Caye has any one taken one or more of these tours if so how was it? How long did it take to get there? Where there bathrooms? Lots of fish, stingrays or other sea life? Over crowded with tourists? Any info would be apresheated, thanks.
