I will be traveling to Bangkok on March 1st and planing to stay until the evening of the 3rd then take the overnight train to Loas to get to Vang Vieng. The thing is that I need to be back in Bangkok on the morning of the 7th. I know i wont reach VV until the afternoon of the fourth, but im not sure how i should get back. I have been looking at flights leaving the morning of the 7th, but Im not sure what time the last buses to Vientiane from VV are. Does anyone have any info or maybe advice. Should I fly back to Bangkok or take the overnight train back. I just really wanted to try to spend a little more than one full day in VV.
