The cruise we went on: Heritage Cruise shorturl.at/nwASX We went in mid December. It is a bit chilly during this time but we caught a glimpse of sun. During the day its warm but by evening you will need a jacket!
That cruise looks so nice and relaxing! If I ever get to make it to Hanoi to visit my sister and my other friends there, I'll definitely have to look into a side trip for a Heritage Cruise! Thanks for sharing!
