Just don’t.
What a hell of a journey! Sitting in the front seat slowly being roasted with the sun in front for 6 hours from Siem Reap to Phnom Penh. No AC, just the fan. We’ve barely left Siem Reap and they stop for lunch which takes nearly an hour with us 3 foreigners waiting by the van while the group of locals sat down in a restaurant and had what felt like a 3-course meal. The temperature outside is 34 degrees while we’re waiting, no one bothered to tell us how long the break was going to be. Nearly passed out from the heat in the van and every time I attempted to roll down the window, the driver would close it straight away making a face and being all moody. Not sure whether that or watching him texting while driving was worse. If it weren’t for my headphones, I would’ve gone mad listening to the shouting and simultaneous clucking like chickens of the 6-7 old ladies behind who thought this was their private ride and not public transport. Will never do this to myself again. Avoid.
