The actual Bioluminescent part was amazing, we were lucky that it was cloudy during the full moon so we got to see the effect. The actual tour started off ok, the driver messaged me through WhatsApp and kept us informed of pick up time. So far so good. But here's where things went bad, the actual boat tour was over sold. They had 10 seats on the boat and put 16 people on it, this changed the weight of the boat and they had to reassign seats to balance that out. Which wouldn't be a big deal, but when you book a trip with your spouse you want to sit next to them. We weren't able to sit together for the trip, and weren't the only couple that got separated. When we arrived to the middle of the lake we were rushed off the boat, they had a tent set up in the middle of the lake so that you could go in and experience the effect even on cloudy nights. But since it was oversold it was pretty crowded in there, and hard to move around without bumping into people. The other issue was the life vest, they had several there but they didn't all have buckles, and since it's pitch black out there it's hard to figure out the size.
I would not recommend this company for a tour, we did several other tours in Puerto Escondido that we booked through our hotel that were amazing. Talk to your hotel and they can usually book trips for you.
My biggest issue was that it was overcrowded, it was unsafe to have 7 extra people on a boat. I understand that September is a slow season for the area, but trying to make up for it with overselling isn't the answer.
Last, we had booked the tour in English, but it was in Spanish. Fortunately we both understand Spanish, but they shouldn't advertise something that they can't do.
