Ok, so I understand that there are some things you need to bring and without them you'd be screwed--something to prove that you can work, insurance (?) for a parking pass.
I have a passport that I intend to bring, so I am all set there, right?
But for the parking pass...what do I have to bring exactly? It's not like the registration/proof of insurance thing that I should already have in my glove compartment? Something else? I am really not car-savvy so I have no idea what I am even talking about, but I saw someone mention if you didn't have [insert item] with you when you check in that they won't give you a parking pass...
