I'd be very surprised if Cambodia doesn't have lanes. It seems to be quite popular with a lot of Asians. I do know, however, that it is a HUGE investment on the part of the owner since this equipment isn't exactly something that is available just anywhere and the wood has to be maintained in a very specific way and this is probably even more complicated in very humid countries like these ones.
It would be a great day out for you and the family though. I hope you get to do it!
