Angkor Wat tomorrow! Will write about it all when I get back.
If I can get away with digging a hole in one of the UNESCO-rated Buddhist towers [a la Tony Leung in In the Mood for Love �������A], I'll certainly unload all my secrets from my jumbled-up head :)

Worrying info from their webpage:

HEALTH:

Cambodia is one of the poorest countries in the world, and this means virtually no reliable medical facilities, doctors, clinics, hospitals or medication are available except in the capital, Phnom Penh. Even here, hospitals can be in very poor condition and badly equipped and medicines are often past their sell-by date or made up of local mixtures of flour and sugar.
If you become seriously ill in Cambodia and require urgent medical treatment....it is essential to get to Bangkok, or at least to Saigon.... On no account should you ever receive an infusion to treat dehydration, as people often die of septicemia which is caused by bacteria entering their blood during infusions. The same goes for blood transfusions....

SAFETY:

Cambodia is a country just emerging from a long period of civil war. The current situation is very uncertain and there may be more violence ahead. Added to this uncertainty, large areas of the country are still mined. It is therefore essential that you stay on clearly marked paths, preferably with a guide. Never wander off a path as you may stumble into a mined area. Never touch any mines, bombs, rockets or artillery shells. They may very likely be live.

Not the best place to celebrate New Year's Eve, is it?
