We are about to live in Luxembourg and for our first arrival at the airport, we need to rent a car.
We are not sure when to do that : is it better to rent the car before our arrival or is it ok to rent it at arrival at the airport ? if the system is like in France, we are afraid to rent the car before seeing it (in France you rent online a car and you get another one at arrival). On the other hand, at arrival (on a thursday) there would maybe not have any car to rent. Taxi would be an alternative.
Any advice for the "rent a car " company I should deal with ?
