Very nice experience, the room is just like the photo on Hotels.com. The food was good, and the activities are interesting. Internet is only available on the top deck, not in the room and restaurant, but maybe it's another advantage for a vacation trip.
The instruction on Hotels.com is not enough, should have more introduction about the activities and agenda, also the pick up information is not clear. There is a shuttle bus from Hanoi to Halong, they can pick up guests from the hotels in downtown. But the service is not included in the price on Hotels.com, we paid 25USD/person for round trip between Hanoi and Halong. It's convenient and safer to take the shuttle.
