As Canadian arriving from Cambodia at the land crossing (Charat, Buachet District, Surin 32230, Thailand) I'm required to have 10,000 baht, (I understand they may require 20,000, at the officers discretion) any idea's if it is possible to withdraw baht from an ATM/cash point, in Cambodia, Siem Reap? Or can I have a combination of USD's and baht? I hear there are casinos at this border in Cambodia so I may be able to buy baht there, as Thai's are crossing the border to gamble? I'm just not in the habit of carry that much baht as I'm traveling overland via Vietnam & Cambodia. Ideas? Thanks
