next september I will stay 3-4 days in LP with my wife, and after we will move toward Huay Xai (Thai boarder).
I know that we have 2 options:
1) Slow boat trip (LP / Pak Beng / Huay Xai / Chiang Khong), 7/8 hours a day on Mekong river, with 1 night in Pak Beng between.
2) Bus trip, Day 1: LP->Udomxai; Day 2: Udomxai->Luang Namtha; Day 3: Luang Namtha->Huay Xai.
Focusing on option 2):
is this bus trip possible during september (rain season, bad roads, etc..)?
I read that each part of this bus trip is 4-5 hours long, is it right?
Is there something interesting to see during the "one night stopover" in Udomxai & Luang Namtha?
Experiences? Suggestions? Is it worth it?
Thank you very much in advance for your opinions!
