We have a 10 am flight on a Friday morning July 2013,and also will need to return a rental car. Is it necessary to stay the night before close to the airport? We have no problem with waking up at 6 am, and are flexible with lodging. Would prefer to stay near Colmar and drive to the airport/return car that friday morning, but can certainly stay at an airport area hotel with transfers.Will need to arrive to check one bag, will have assigned seats from EasyJet going to BUD. I just have no idea what the traffic might be like in either direction.
