Hi Mo,
Thank you for your post - it sounds as though you had a great time. I mentioned on another thread that I have been to Cambodia (& Hanoi) previously and it turned out to be the hidden gem and the attraction of this tour is that all movement in the country is on the ground (last time I flew between locations) so you see a lot more of the country & the people. Laos is a first for me.
A couple of us are well used to going bare footed.
I know what you mean about the genocide museum but am interested that you got to the killing fields as that was not an option on my last tour there.
I can easily pass on the shopping - more time for photos!
Also interesting that you got to go to Halong Bay as I would certainly be interested in this - a great day out.
Ian
