I saw that others spoke about their experience with Con Aer Lingus, but I thought I could speak to Going North!
It used to be that you could easily slide up to the Northern Border with just a
driver's license and a smile. But lately, they tend to be more serious. They might let you across with just a driver's license and a birth certificate if you're really simple to figure out (no kids, no funny smell in the car, mainstream look). Or, they might make you pull in for a closer look at the car. IMHO, you ought to have a passport in today's world. Sure, the U.S. is pretty far away from trouble on a consistent basis. But, if you wanted to get across the line during tough times, you don't want to be shoved into the group (the 90 percent) who don't have sufficient paperwork.
Anytime you cross a sovereign border, you should have a current, valid passport with a certified copy of your birth certificate. Plus, be aware of other paperwork you should have if you have adopted kids or other complexities.
On the easygoing side, I found that the easiest way to get money while out of the country was to just carry a bankcard. It is so easy, while I was in Spain, France, and Italy (and up in the Great White North), to just pop the card into a teller machine like I was here in the States, and get local cash. Hope that helps!
