An excellent trip on a comfortable boat with a good crew and good food. We saw all of the expected wildlife, and snorkelling with sea lions and turtles amongst the fish was a particular highlight.
The boat is not operated by Explore, so on my trip there were other nationalities who had booked through other operators, but it was a good mix. On the afternoon of the first day at the hotel I received a WhatsApp from the cruise operator providing details of the airport transfer (handled by the hotel in my case) and of their representative who met me at the airport to provide my printed boarding pass and Transit Control Card. They also helped with the additional baggage check required before bag drop. The message also includes the flight details if you want to complete the bio-security form at https://declaracion.abgalapagos.gob.ec/ before arriving at the airport.
After snorkelling the crew will rinse all your gear and then hang wetsuits to dry (I think it was 80 USD to rent a wetsuit on board for the six days, but masks, snorkels and fins were free). There are lines with clothes pegs on the top deck to dry your swimwear.
Remember to take USD cash for tipping the crew and guide at the end of the trip. Two envelopes were left in my cabin for this, but the amount suggested at 15 USD per day for the guide and 25 USD per day for the crew of 11 was about double that in the trip notes.
