Just come back from a fantastic five week trip to South America. We (sister and myself, early 20s) completed a fantastic eight day / seven night cruise of the Galapagos Islands with Aida Maria.
When researching our trip to the Galápagos, there were not many recent reviews of boats. Our criteria for the trip was based on dates, cost and itinerary. The Aida Maria met those criteria, so we hoped for the best and booked our 8 day/7 night cruise over Christmas. We booked directly with Aida Maria Travel. The following was a great resource for researching cruises: http://www.happygringo.com/ecuador-travel-tours/galapagos-travel-cruises/galapagos-yachts/index.html
The boat was well maintained and our cabin was clean, but a little small. There was little room for luggage, so pack lightly! We were fortunate in that we had a main deck room and could open a window. I believe the rooms lower deck were noisier and smelt of fuel due to their location near the engine. We used the common outdoor areas when navigating between islands, but there were also seats indoors to use during free time.
Food was plentiful and tasty, though simple. Had seafood at least one meal everyday, with lots of fruit, rice and salads on the side. Breakfast was generally eggs, cereal, toast and fruit. They made a special effort Christmas Eve with a whole Turkey for dinner. Impressive when you saw the size of the kitchen!
We covered the northern, central and southern islands of Galápagos in our cruise. We saw lots of birds and most land animals. Snorkelling was a little disappointing due to poor clarity and not a lot of fish, but as Australians we have been fortunate with some excellent snorkelling experiences in the Great Barrier Reef. Most days we did two land based trips and two snorkelling trips. The boat had two pangas so all 16 passengers on board could get to the island in one trip. Land based trips generally didn't consist of long walks, but rather short meanders on the beach, with our guide stopping to tell us about the animals, history, or plants. The boats itineraries were all well organised so landing sights / walks / snorkelling sights were not overrun with tourists.
Due to the large distances between islands, we were often navigating at night. The boat was reasonably small and rocked a lot when moving. If you suffer from sea sickness, ensure you pack medication.
The crew didn't speak much English, but they were very attentive. Our guide was informative and helpful.
Overall we had a fantastic trip. We both felt that 8 days was just the right length - any shorter and you feel as if you have missed seeing lots, but any more than 8 days in a boat would have been a little too long for us! We also both felt that a boat trip was the way to see the Galapagos islands. The distances between islands is large and by cruising, you maximise the time available on islands to see the flora and fauna.
