We booked a full day tour with Thalia. I had a few things I needed in the lead up to the day, she was helpful in helping me change the number of people attending and answered my questions. On the day she was wonderful. There was 10 of us on a VIP snorkelling tour down to Yelapa, and she was so accommodating to our group. She is highly qualified in marine life, so she was able to provide all sorts of information about the environment and the animals we encountered. In Yelapa she provided a lot of information about the town and its history, and even helped some of us negotiate purchases of goods with the locals! The place we went to for lunch was sooooo great - a seafood restaurant on the beach in Las Animas. We had the best day, all of our group was raving about the tour and what a great time we had.
