Excellent is really not a good enough rating for Mari! All of our guides onboard the Celebrity Experience were wonderful, enthusiastic, helpful and caring! After our first ride with her, I have to say that Mari really was the guide we wanted to be with and also the most talked about. Her knowledge and expression combined with her delivery of her information in an almost theatrical way, with honesty and sincerity definitely elevated our excitment of this once in a lifeime trip. I mean, you would think that the unique experience of being surrounded by the nature of the Galapagos could not be improved upon, but you would be mistaken, as Mari's way of 'running' her excursions was calm and relaxed and at the same time gave just the right amount of seriousness so that it kept us on our toes, ready for the next wonderful experience. With her guidance and synergy with the zodiac driver (all of them just as exceptional as our guides), we checked off "To-Do" and "To See" items from our top wants at an alarming rate! We really could not have asked for more of a guide. Her love for Equador, the Galapagos and her job were apparent in absolutely every aspect of her personality She the real deal,a good egg, and its our hope that our paths cross again.
