Yes, I arrived there by car. The hastlers were banging on the windows. Tell them you travelled to Cambodia before and you will be left in peace. At the Cambodian side they offer you a free bus to the "busstation" of Poi Pet a few kilos outside town. There is nothing there but an empty hall and they will tell you to change money at a scam exchange rate, because, they tell you in Seam Raep Thai money isnt accepted. Besides they try to get you in an expensive taxi. Dont change money there and take the bus.

we have recently been through the Poipet crossing, arrived Aranya Prathet and took a tuk tuk to the border or so we though. A building which even had a big sign saying Cambodia Visa office and the same scammers in uniform - luckily we had read warning like this and insisted they take us to the border which was another 3 kms away. Before we left we had the usual stories of how we won't get into Cambodia and we would have to go back to Bangkok. Ignored all this rubbish and walk through, the queue to leave Thailand took longer than the queue to get a Cambodian Visa. We then walked outside to dozens and dozens of taxis, bikes, tut tuks etc. I got a taxi to Siem Reap for $20 yes $20. They tried to scam us at Siem Reap but thats another story but lets just say they failed again. These warning are really useful so we thought we would add our feedback - our trip was 23 Nov 2009.

We recently went through the Poipet crossing. We thought we'd be sweet with our visa since we had obtained a Cambodian e-visa in advance. We had read about the scams at this border but we were very unexperienced and hadn't come across something like this before.
So the tuk tuk driver dropped us off at a 'Cambodia Visa office' like the one mentioned before.... And they said they had to check our e-visas, check that our passports etc were in order. It cost 200 baht each. We ummed and ahhed about it because we never heard about it, and thought it was a scam but weren't too sure. The clincher came when we took too long to decide whether or not to go through it, and I was going to walk to the actual border while my partner stayed there. The guy said that if we did that he'd charge us 400 baht each. So we left!!
