Has anyone used www.mekongrivercruise.com for a trip to Vietnam and Cambodia? I was wondering if they provide good drivers and guides for a 16 day trip around Cambodia & Vietnam on Pandaw River Cruises? I want to save time on getting to the different places I want to visit. And also, are they flexible enough to allow us to bend the itinerary and do our own thing during the entire stay? I would love to hear feedback from others who have tried their service and would love to hear comments. I don't want to spend too much on a company that doesn't deliver. Thanks in advance!
