Don't worry too much about it. There probably is only a small amount of head space in there anyway, so you should just increase the pressure in the keg a bit before leaving if you are worried about it. I'd just turn it up to maybe 30psi or something. Whether that amount diffused into the beer from the headspace, or some amount left the beer, either way it won't really affect the over carbonantion level much.
You can carbonate a cooled, uncarbed keg and be ready to drink in maybe 4 hours or so anyway. Once it's cooled down, turn on the gas to your desired level, and shake the keg back and forth until you stop hearing gas exit the tank. Then just set it aside and wait for it to calm down before drinking.
