Apparently the transportation to the airport is a dilema by train or cab. Someone else advised not trying to get a cab before 10:00Am and the ticket needed back to the airport (metro ticket is not appliable) What do you suggest? Where do you purchase the ticket to the airport? It is our first trip we are staying in Marais and leaving on a Sunday morning. We obviously do not want to miss our flight. Thanks for any help and assistance. Karen
