I recently took my 4'th tour in Vietnam with this same agency. They arranged for my Visa on arrival at the airport, excellent drivers and guides, my hotels, and all of my tours. I took my ten year old son from Saigon to the Mekong Delta. Vietnam Paradise arranged a cruise with an overnight stay on a refitted junk up the Mekong, tours to small villages along the way, transport by car to Can Tho, a speedboat from Can Tho to Phnom Penh, Cambodia, another car and driver from Phnom Penh to Siem Reap and Angkor Wat, and the return trip to Saigon. They were completely flexible when we wanted to stay longer in a place or to skip a destination. I travel quite a bit and of all of the agencies I have used around the world - these folks are the very best. I priced out all of the components of the trip and thought about making the arrangements for the trip myself - but their price was less than if I had booked it myself.
