Booked the afternoon before, and the order was confirmed in the evening, with the meeting point informed by email. Staying in Cat Ba town, it took five minutes to walk to the meeting point the next morning. First, guests are picked up from each hotel, and then we go to the pier to board the cruise ship. The first stop is a village tour, with free small fish foot massage and bicycle riding, with about an hour of free time. Electric cars pick us up and return us to the cruise ship. The second stop is swimming, where guests can swim freely, or lie down on the cruise ship if they don't want to swim. Then lunch, buffet style, the food is fresh and delicious! After lunch, we first return to the port to drop off the half-day tourists, and then pick up a group of afternoon half-day tourists. Then continue to sea, the third activity is a double kayak, about 40 minutes, with almost no wind and waves, very safe. Back on the cruise ship, continue sailing for a while, and then we arrive at the afternoon swimming spot. Freely choose whether to go into the sea, if you don't want to go into the sea, you can have afternoon tea on the cruise ship, free tea and fruit. After a short break, the cruise ship slowly sails back to the port. The tour guide arranges shuttle buses to take everyone back to the hotel, stop by stop. A day trip, the itinerary is very rich, but very leisurely.
