Don’t Worry About What You Forgot!
Going to Europe is not like going to the moon so Relax! Just take the one last look to be sure you have your passports, your confirmations in a way you can get at them, and at least one credit card. I keep a plastic file folder with my important papers. I make a copy of my itinerary and put that as the top page, a copy of my airline reservation, and any written confirmations from hotels, cars, rail or tours. Since we recommend you sign up for something special in advance as a highlight of your trip, we hope you have that confirmation. You can even mail yourself your online confirmations that you received eight months ago so they are on top in your email inbox!
