We used Tuan's services twice - once for a large group family tour with age groups ranging from 94 to 4 and he took care of everything- home stays, itinerary, appropriate breaks, food etc. Had an extremely pleasant journey. He goes out of the way to arrange things and was like a family member. 

We then used his services to arrange a triple for my best friend, traveling with a toddler. They had a great time too.
