Hanson, our guide, was very professional. The jellyfish in Jellyfish Lake were truly beautiful and unforgettable. Swimming with sharks in Shark Bay was highly recommended. The BBQ lunch, giant clam, Milk Lake spa, coral, and tropical fish were all excellent part of the itinerary. If you can swim, I suggest renting fins; it's less strenuous and safer!
