We had really good experience in cruising Halong Bay that was the high point of tour in Hanoi. The cruiser Ancora was a wonderful ship, 5 stars and less than one year old and gave us the enjoyment that was more than expected.
While city tours were not much impressive to us ( as we have indicated that Vietnam cities are not much different from other Asian cities ), we have learned a lot of Vietnam culture by those tours.
Above all, you have arranged a really good tour for us. We would like to write some comments on TripAdvisor.
