For the price paid, there's really nothing to complain about! We were a family of 4 with a 2D-1N stay. The 3.5-hour ride from Hanoi was very long!!
The cruise itself was good, food was decent, guides were fun!
Rooms were not the best, the beds were not very clean and the AC was not working properly.
You also need the key to lock the room from the inside, so you cannot really split up from your partner or room buddy.
