This summer I'm planning to go to Thailand, Laos and then through to Vietnam. I know very little about this. I was wondering if somebody would be able to tell me if this could be done comfortably and affordably in 3 1/2 weeks. I would appreciate it if they could also give me some ideas about the route.
I am flying from the UK to Thailand where I hope to get the rest of the way by ground. I am really interested in visiting Vaing Vieng and Luang Probang and then take the Mekong river and visit Hoi An, Nah Trang and Ho Chi Minh City. I know little about South East Asia and would really appreciate some help.
