There are just two difficult things:

1. You'd have to study the regs a little, as they differ from country to
country and from the US.

Do the rules differ in any real way, or are they just goofy little
regulatory differences that have no immediate impact on most real
flights. (For example, if Belgium's VFR cloud restrictions are
different than France's, it's just a "gotcha" on a test, rather than
anything "real".)

What does a rental checkout involve? Will (for example) a German FBO
be comfortable renting Mary and me an airplane for a week? How about
if they know I'm going to fly outside of Germany?

2. You'd have to pay more than you are used to.

Okay, so it sounds like renting a plane for a flight around Europe will
cost at least 100% more than flying Atlas here in the States.

Sound about right?
