I have backpacked extensively back in the day. Having done SE Asia 13 years ago we were excited to go to Vietnam and share the experience with our young children. Trip Advisor is an amazing resource...we managed to travel from Hanoi, Sapa, Halong Bay, Hue, Hoi An, Ho Chi Minh City, Mekong Delta, Phu Quoc Island. What an experience and a great itinerary. I was worried before coming about how to deal with transfers and taxi scams. The first hotel quoted $165 pick up at Hanoi airport to our hotel. The transfer prearranged through Hanoi Transfer Service was $16. They were efficient always priced correctly and showed up on time in clean cars. Mr. Chinh & Lily were our liaison and wow- amazingly made out trip worry free. PM me if you have any questions. We spent 16 amazing days at all levels of travel and once again at the backpackers level met very cool people while in the 5 star stays we enjoyed the surroundings.
