Have you ever been in Laos or Vietnam? (Luxembourg)

I am going to spend 2 weeks backpacking in Laos and Vietnam in mid-December. It would be great to have a fellow-traveller(S) to share the sightseeing and hiking. The plan is so far: Luang Prabang, Sapa and Hanoi… may be Hue. Details will come soon - I‘m in process of organising it 

Let me know, if it sounds interesting. Or if you have been there already and have some useful advice to share.
