tour guide jack was really nice to us, and their photographer was very professional and took amazing shots of us. the cave experience was the best. There was a breakfast buffet before getting on the boat, which set of at 9:30am for the big boat so there was more than enough time to get ready, toilets at the breakfast buffet place is clean as well. Overall really good experience. My friends and i were the only english speaking tourists, and Jack and his team made sure to explain to us to his best abilities, and made sure we understood his guidance as well. Definitely worth it!
