My husband and I will be arriving into IAD on Sat. 20th Dec. with Icelandair at 7pm.

Now for my questions...

How is Immigration on weekends and does anyone know which terminal Icelandair arrives at?
How far is the car rental section? Do we need to take a shuttle to get to it or?

We are driving to Philly and I am wondering if I should just book a hotel for the night in case immigration lines are long. We would be going through the US citizen line. We have been there once but it was years ago and only for a layover. Hoping things would have gotten better but heard such horror stories about IAD in regards to lines so I am just unsure as to what to do.

Which app do you recommend for finding a hotel for that same night. I really hate booking last minute but if we get out of there before say 8:30...we want to just drive to Philly but any later...no.


I'd be grateful if someone out there could offer some info./tips.
