Hello there, I'll be starting my RTW trip from Beijing down to bangkok crossing more or less the same countries but in opposite direction.
I believe it may be a good idea to exchange our contacts for suggestions (each of us will probably will be in the place where the other's just been). We may even meet somewhere around during the way :-)
Please have a look at the details of my trip on my website:
You can contact me here or within my website itself (there is a "contacts" section)
BTW: why did you put machu picchu pictures if you are travelling through asia??? :-O
