Had a wonderful time on the Nautilus! Dennis and Martin were both excellent guides. Knowledgeable, funny, and friendly! So much better than just snorkelling.

Best tour of the vacation! Martin and Dennis were great. Martin was funny and still informative. He kept us all captivated and laughing the whole time. Dennis was fun and did the diving.

Yes, but if you can hold it I recommend that you wait. The bathroom is in the center of the way to get in and out and well, everyone knows your in there. Haha - but if you gotta go, well it is there!
