Hi we are an expat kiwi family currently living in Phnom Penh Cambodia. What an awesome trip!
I dont see any links for Cambodia, are you coming here? Or Vietnam. Both are just a hop skip and a jump from Thailand and well worth the extra boarder crossing.

Thanks for your two comments, and we are defintely thinking of going to Cambodia, Vietnam and Laos, I just haven’t researched them yet. I’ll head over to your blog for a look…
