We travelled with Quasar Expeditions and found them to be an excellent company. The highlight was a seven day stay on the M/Y Grace. The ship was stunning in every way, delicious food, wonderful staff, excellent service. The attention to our comfort was truly amazing: from the Captain welcoming us back on board, drinks on deck, hot tub and drinking chocolate after snorkel was a great treat The guides was excellent, detailed briefing every night made sure you really knew what you were seeing and experiencing. The small groups and detailed commentary meant we really learnt a lot about the animals, plants and geology. The content was top class for anyone with prior knowledge or who had done lot of preparation. We extended our trip to drive from Guayaquil to Quito and apart from altitude sickness as we reached 14,000 feet we had a wonderful experience. The hotels they arranged were gorgeous, especially, the MaisonAlcazar. beautiful Cuenca. We had a very thoughtful and knowledgeable guide called Franco there. We would wholeheartedly recommend using this company and I tend to do so ourselves.
