If I am away for a longer period of time, I much prefer the Sofitel park and fly packages. I have a relaxed evening before the flight, and my car is fairly safe in a covered underground garage with access restrictions.
For a few days, short term parking (somewhere well away from all the other cars

) is fine, but anything more than that I use the Sofitel. There are some excellent spaces there, which are actually large enough to fit my car and don't have people banging their doors into the car either.
