For anyone who has read: http://conference.apnic.net/34/travel#venue and is expecting a nice cool 22c maximum and 9c minimum as the webpage suggests, will be in for an unpleasant surprise.
I will be sending some more tips about Phnom Penh over the next week or so and am also in the process of setting up a little website with some tips for getting around and generally surviving well.
If anyone is looking for more hotel options nearby, let me know. I can also help with any bespoke tours that people might be interested in. A couple who have been family friends for years run a little local travel business, normally catering for big groups, but they are happy to look after the needs of anyone - and they speak great english too (rare here).
I will have the blog with tips setup over the weekend!
