We know that there are far too many places on the globe to see 'em all. We simply won't have enough time. Luckily, we have done a pretty good job so far as this list of visited countries indicates, but there are dozens and dozens of cities we'd enjoy seeing.
We could surely check off a few of them on a cruise in Northern Europe. We picked up some traditional brochures and adopted a consultant. Even checking the various itineraries can be fun. It would be marvelous to fly through Iceland to get to a cruise like this next summer.
