My better half is flying in on a red-eye flight from states to Santiago and is scheduled to pick up a rental car. We've rented a car before, but flew into PUJ. Will the car rental place be open in the wee hours? Should he just hang out at airport until sunrise to avoid driving at night? We've experienced East Santo Domingo at 5 PM...and he's prepared for that adventure again, but, we don't want to risk everything because a cheap flights.
