As your international flights will almost certainly be routed into BKK then it would make sense to meet there. Also, whilst there are direct flights from CM to Siem Reap, it may be cheaper to route through BKK and then to the north.Check out the Air Asia site as they are likely to be cheapest. You do need to book ASAP as Xmas is a very busy time and fares are only likely to rise from now. It is possible to go overland from BKK by train and bus. Train to Aranyabprahtet, cross the border to Poipet and get a bus or taxi from there to Siem Reap. The border crossing is "interesting " and you do need to keep your wits about you so as not to get recommend or pickpocketed. A fun trip, but probably better to fly if you can get a decent fare.

Chiang Mai to Chiang Rai is a 2 hour bus trip or you could rent a car which would give you a lot more flexibility to get around. Getting back to BKK can be done by plane or overnight train, probably for around the same cost.


www.hostelworld.com and www.hostelbookers.com are great sites for sourcing accommodation, the sites are easy to use and efficient. The reviews are usually very accurate and they book not only hostels (I.e. with dorms) but small hotels and B&B s as well. Last time we stayed in CM we booked 3 Sis B&B and enjoyed our stay there. Spacious rooms, helpful staff and a good location.

Actually, I don't think there are flights between CM and Siem Reap any more, and AirAsia still doesn't fly from Thailand to Siem Reap. The only option at the moment is Bangkok Airways.

My own preference would be to go to Angkor first, and then use the time in CM / CR to relax and unwind after that.

Don't worry about the onward ticket thing. They never ask to see that unless you're from a poor country.
