I approached Hanh at Tonkin Travel about 2 weeks before I planned to travel, and incredibly, within that short time he was able to accommodate all my many requests. My husband and I travelled for three weeks across Vietnam and Cambodia and everything ran like clockwork. Countless transfers and travel arrangements always went according to plan. A great itinerary and the guides always tried to make sure we saw things at the least busy time, and if we got tired and didn't feel like doing something, the guides let us change things around with no bother. In Halong Bay, we joined a larger group to go on a cruise, which was lovely to chat to others. I think previous reviews mentioned this as some kind of failing of the company, but really who wants to go on a cruise completely alone? Also, Halong Bay is such a huge tourist attraction with all kinds of licenses required for each boat, so you just wouldn't get to cruise on it at all if you didn't go with a group. We went on the Dragon Pearl which was just lovely, and we still had only a few couples with us and a very quiet bay. It goes on the west bay, which is quieter than the other bay. We were covering a lot of ground in our itinerary, so initially (Hanoi, Halong Bay, Moon Garden) there was A LOT of driving between sights. I highly recommend booking at down week in the middle of your trip, or a couple of extra days in one place (Moon Garden?) so you don't feel like you're constantly on the run. We enjoyed a week in Hoi An, both in the Old town and on a beach resort just a few miles away. All hotels were very central and clean, with really amazing food! A couple of the tours included stops at things like a brick making factory or lantern making, which weren't very interesting to us, but the guides would be happy to change if you didn't like. All the guides were very friendly and eager to help. a few were either not great english speakers, or didn't have a great deal of knowledge, so we supplemented a few tours with reading and research of our own. But most were incredibly knowledgeable and could give us perspectives on every day life and politics and customs, which was very interesting. One night we were returning from a trip when the company gave us free tickets to the Saigon Opera House, which was a lovely surprise! All in All, when I think of all the endless arrangements that had to be made, to make this trip possible, I feel it was incredibly good value for money, so I would highly recommend!
