I do not like PG's monopoly on the BKK-REP route and refuse to pay the near £300 return flight back into BKK.
I am thinking of doing BKK - PNH on AirAsia and then get a bus/taxi to Siem Reap. I don't think I want to stay in Phomn Penh though, so I will be going straight to Siem Reap when I touch down.
Does this sound like a realistic itinery?
I read somewhere that it takes 5hrs by AC bus from one city to the next, and the route is safe and one of the better roads in Cambodia.
FWIW, I will be flying AK (or MH) REP-KUL on the way out.
