Just the first night (we will arrive @ 10 pm on saturday, after we´ve been through every institution on the airport it might be sunday) is a problem.
I´m going to order a rental (pontiac g6, we are both under 25, still 24 and don´t get the mustang so far) for sunday morning or even in the night to sunday. We´ll have to spent some hours on the airport then.
During the rest of the "car-holiday" we want to stay at motels, if we find them early enough
Of course, if someone has a place to sleep we wouldn´t say no. We are not demanding any luxuries.
