What people love about 3 week South East Asia tours
- Indochina Tour with Bangkok Extension 21 Days
We had 21 wonderful days in Vietnam, Laos, Cambodia and Thailand. Every time we arrived in a new place, there was always someone waiting for us. This really comforted us a lot. Reduce our nervous feeling in a totally strange place with no language understanding. We were picked up from the airport with our luggage stored in a van every time then assisted on hotel check-in and toured with our private chauffeur and tour guide. Our tour guides are very professional and knowledgeable about their country and history and made us feel very welcome and relaxed like touring with old friends.

We went on our gold anniversary vacation to Indochina... never, ever had such a memorial experience!! Bravo Indochina took care of the minimal details, we were looked after on our flight connections, our accommodation decisions, it s very well recommended by our tour manager Tien Tran, and incredibly guided in each of the four countries! We are recommending Bravo Indochina Tours to our friends

Thank you for so much help before the tour and the wonderful staff you provided to make our trip something we will always cherish! I would love to give feedback on each of our guides but cannot remember their names (Suggestion: It would be helpful if that information was included on our itinerary or the guides provided a card with their names on it when we met them.) Some of them were outstanding with their English and did a wonderful job directing us through the sites. It would have been helpful on the first day/night to give more detailed instructions as there is so much going on that it is hard to take it all in. Example: We would need to check out of the hotel by 7am and take our luggage with us on the tour. It would also be nice to know what we are to do about breakfast as the first day our tour left at 7am but breakfast was not available until 7am. The staff at Grand Alpine would not accommodate us and told us we needed to speak to our tour guide (who, when I asked, told us that we would have a box waiting - which didn't happen.) The rest of the tour was wonderful and we felt very cared for. It was just that first day that was a bit of a challenge. We will always remember our time in SE Asia and smile:)
