We will be on a vacation March 2010 in SE Asia. We have 15 days on the ground. The first 7-8 days will be spent in Cambodia. We depart from Bangkok at the end of the trip and will spend at least one day, maybe two there for catching a night flight back to the US. With only 4-5 days left for Laos, is it worth the travel hassel and expense of an extra flight segment to stop in VT for only 1 or 2 days? Is there much to see there that we haven't already seen in Cambodia? Should we just spend all of the Laos time in Luang Prabang? We will be using a BA Discovery Airpass to get around.
