My friends and I join the 2 days 1 night tour with Alova after being recommended by my hotel. We really enjoyed ourselves although we spent about an hour or so waiting for other guests to arrive on board. During that time, we had the entire cruise to ourselves and it was very nice and peaceful and we enjoyed a very sumptuous lunch. And of course, our guide, Manh, kept us entertained throughout. 

The tour included pick up and drop off in Hanoi city and the driver was very safe. Also, all meals prepared on board were very delicious. Oh and happy hour is a must onboard. 
The tour was of a good size, only 15 pax. Our 2D1N was of 8 pax and we joined another 7 pax who was on a longer tour. 

Oh and the room was excellent! Nice and clean with big bathroom. 
The staff onboard, including our guide made the trip very memorable. I will definitely recommend it to all my friends.
