Sounds like a good enough route - the only "hard" part will be Laos to vietnam - it can be a bit of a doozy if done overland.
Meeting people - No doubt you'll do BKK>Chang Mai & Surrounds>Luang Prabang in Laos by mekong boat>Vietiane>Hanoi>HCMC>Phnom penh in Cambodia>Siem Reap (Angkor)>Thailand. Its a pretty popular route, every destination has its traveller ghetto's and you wont be the only white face on the travel routes either, so meeting people wont be an issue.
Visa wise, you can get Laos and Cambodia at their respective borders, Vietnam do up front (I'd suggest doing in Laos at their Embassy in Vientiane).
Think your biggest thing is theres alot to see and do in the 5 weeks you have... |
