Halong Bay is a must and Gray Line Halong Bay Cruise were a great way to see it. The bus trip - Trang (our guide) was so lovely, she made sure the 3 hour trip from Hanoi went by quickly with lots of local information, stories and a game or two. The rooms on the boat were so fresh and nice, everything we need. The bay is amazing and a must see. There were only about 24 people on the boat so it was easy to chat and meet some interesting travelers. The food was great, the captain made sure he knew everyone and made us all feel welcome. The only down side was with so much to see and do on the bay, I would have like more time just relaxing on the boat but it was made clear that it was our choice and there was no pressure but we wanted to see and do as much as we could.
