Inquiry Submission By Dunoontravelbug

I will be travelling to Cambodia on my own and would like to cross the border with Vietnam from Ban Lung to Pleiku. Is this safe for a woman to do alone and how would I do this. I want to keep costs down and not take up huge amounts of time. Also what is the best way to make the 8 or more hour trip from Phnom Penh to Ban Lung?
