Bel,

I used Sinh Cafe's bus to go to Phnompenh. You can buy visa to get to Cambodia at the border.

From Phnompenh, I took the boat (takes 5 hours) to Siemriep which costs 25 USD. Should not take bus to from Phnompenh to Siemriep because the road is so bad.

From Siemriep took bus to Bangkok it costs about 20 USD (i cannot remember exactly), but normally you should check around for several agencies before deciding for the best bus (cause different agencies tell different price). The road from Siemriep to the border of Thailand-Cambodia is very bad, takes 10 hours!

You should/must buy the Lonely Planet book to be able to get around in a easy manner, and to save money!
