In Iceland, you can sleep soundly knowing that you won't miss a northern lights display. That's because some hotels have equipped their room phones with a special button for wake-up calls, labeled either "Northern Lights Wake-Up" or "Aurora Wake-Up." How cool is that? (@meganhomme/TT)
P.S. Since we're on the subject of auroras, I just recently learned that in the Southern Hemisphere they are called "aurora australis," not "aurora borealis." The latter only refers to the Northern Hemisphere auroras.
