Trip Advisory proudly claims to be the best site for information; with over 10 million views per month, it certainly is a busy web-site. But relevant? It's mostly for looking for hotels. They do however have a good forum:
'The traffic in PP is insane and road traffic accidents are common. I met a guy who had his ankle smashed when someone crashed into the back of the moto he was on - so tuk tuks would be a safer form of transport'.However most forum postings are on Siem Reap and good tuk-tuk drivers (are there any?).
