It's true that document verification can be much more stressful than packing, especially when thinking about a trip outside France. But honestly, it's not a matter of 'more or less stressful,' but rather whether you have time to fix problems. If you wait too long, like the Dupont family last year for their trip to Canada, realizing that a child's passport is expired just before departure makes things much more complicated than a simple forgotten toothbrush. The real issue is the response time of administrations, not the act of verification itself.
