We bought a train / bus ticket at Bangkok train station for the train of 13.05h and arrived aprox. 18.30h in Ayanaprathet (almost an hour later than scheduled) We expected a bus to be waiting at the train station, but there was nothing. We showed a tuktuk drive our "bus ticket" and he made a call, said there was no more bus. We already booked hotel in Siem Reap for this night, thus we had no choice. The tuktuk driver took us to a "visa office" at no charge. Luckily we had obtained an eVisa ahead. Because there was no more bus, we had to pay 1000 THB for a private taxi. Another guy joined us towards the Poipet border. He asked us to get some money, but the ATM only gave THB at the moment, which we did not needed at that moment. We got our passports stamped by customs and the guy wanted to take us to ae money changer. We refused, he got a bit pissed of,but took us to the taxi and did not need Cambodia money at that time and just wanted to go to our Siem Reap Hotel. The taxi took us to the city limits of Siem Reap, said he was not allowed to take us to the hotel. A tuktuk driver was waiting for us take us, and was very friendly in the beginning. His mood changed quickly when we did not want him for tomorrow to the Angkor Wat area. He took some detours and stopped in a dark place to persuade us to hire him the next day. We only had some small Thai money, no USD or riel at that moment. We just want to sleep and explore Siem Reap by ourselve. Finallly he took us to our hotel, refused the thai money and began shouting and threatening us. A bad experience I wanted to share with you. We left Cambodia 3 days later by plane and enjoyed the rest of our holiday in Thailand, which is much better organized. Tip: go to tourist information office and arrange your trip to Angkor Wat there and you will be save.
