I%26#39;ve been down in that area on two seperate trips. First trip I opted to go by bus- night VIP bus from VTE to Pakse. On the way back I broke up the trip with a day %26amp; night in Savannakhet. This Sept. I took the VIP bus to Pakse agian and flew back. If your time is limited, you might opt to fly.
