So I made it...after almost 24 hours on the go!  Guest house is not bad.  Has aircon that works and although the shower is hand held, at least it's not boiling water and washing out of a bucket.  Been out with Jon from the charity this morning driving around Siem Reap and about to set forth and explore on my own on foot!!  Hopefully the GPS and maps on my phone will get me back to my starting point.  Otherwise I will need to leave a trail of flour behind me to follow back!! And although I know you don't want to know this,  it is hot, hot, hot and sunny!
