Sailing on the Carnival Dream in February, and wanting to do a dolphin encounter excursion (where you actually swim with them). Can someone recommend one for me in either Belize or Cozumel that will let you take pictures with your own camera, instead of being forced into a photo package (for an cardiac-inducing amount of money) if you want pictures. I know some places won't let you take pics with your camera. Thanks in advance!!
