Just got back from a week in Cambodia flew into PP and then took fast boat up to Siem Reap, 2nd time in two years for this trip. Cambodia is an incredibe place to travel if you don't mind ruffing it abit. Thai, Bangkok Airways, Roayal Cambodian all fly from Bkk to PP. I flew Bangkok Airways from Bkk into PP and then flew from Siem Reap back to Bkk. Paid Us $222 for airfare. Have to do at least 3 days to see Angkok- even that is not enought time to really see everything.
