I've paid a Cambodian man and a Vietnamese man 4,000bt a day for a 3 day trip, once to one of the islands and once to Phnom Penh, plus I pay the bar off fee plus all expenses of course. To them it's the whole package that they assess - 12,000 bt and a mini trip to somewhere they haven't been before. They were happy enough. When I'm fond of the lads they only need to say they've never been in a plane and they've never been to wherever and I say: 'Let's go'.
