From Hanoi to Ha Long Bay, to Hue and Hoi An, and then from Ho Chi Minh City and up the Mekong River through Cambodia and on to Siem Reap and the wonderful Angkor Wat – Asia Pioneer organized this three week holiday for four friends – all of it with tremendous efficiency, terrific guides. Mr. Lam was always available, always helpful and clearly knows his business extremely well. Would not hesitate to recommend.
