Pre departure preparations

My departure date of 28th February is coming up fast! My destination is Siem Reap and Angkor Hospital for Children (AHC) where I will (hopefully)be of some  help looking at their accounting procedures. My flights are booked, travelling  via Kuala Lumpur and I have my visa, which was surprisingly quick and easy to obtain on-line in less than 24 hours. I have bought a Learn Kymer cd-rom and I am struggling to try and learn a few basic words before I leave. This is proving to be quite a challenge!!
