The tour was well-arranged by the tour operator in Hanoi. The guide's name was Ken. I forgot his Vietnamese name. But he is professional and very energetic. I suggest another guest should upgrade your food to all you can eat, rather than a set menu (included). The foods are sumptuous, such as prawns, shells/clams, chicken, fish, many fries, and desserts. I took an optional tour of Halong Bay on a speed boat (USD 10/ person) and a bamboo boat (USD 2/ person). It was so lovely and recommended. I am not a hiking person, so I am not going up to the SURPRISING CAVE and TIKTOP Island. I just enjoy most of the time on the boat. The cruise boat is clean and comfortable. I am onboard OTIS Cruise boat (the name). Thank you
