We also did the Panama Canal on the Coral and found it to be an awesome experience! As you begin to enter the locks they have someone giving a narration over the loud speaker all about the history, etc. It was very early for us, the sun was just coming up and everything was so still & quiet as we approached the locks. Really found it fascinating, I would recommend it to anyone and look forward to doing it again but.... of course this is JMHO!!
