I want to take a tour of Halong Bay, staying overnight on a boat, for 2 or 3 days. I have found that Sinh Cafe in Hanoi offers these tours, but does anybody have any recommendations on a specific tour or company ideally in Hanoi that provides transportation to Halong?

Our family used Columbus Travel in Hanoi for a very successul Halong Bay adventure. Good leaders, good food. Our 2 kids felt adopted by them. Do the kayaking!
But, as always, that was just our one experience.

I used the Kangaroo cafe in Hanoi. Very good, transport and boat trip all sorted at a good price. No problems at all. Beware though, apparently there is a fake Kangaroo cafe, the real one is run by an Australian, fella of around 50(apologies if Im wrong with the age) nice bloke.

I took the Sinh Cafe tour booked via my Hanoi hotel. It was fine ...twin beds with ensuite with shower. $57 for 1 night with 2 lunches, dinner and breakfast and kayaking. All the meals were fine but not excessive except the breakfast which was passable but the lunch at hotel on land made up for it.
