We had a more-than 24 hour journey, from Curaçao to Miami to London to Zürich by plane, and then to Lucerne by train. It seems as though this kind of trek only gets harder as we get older. The ever-shrinking seats on the planes don't help, that's for sure. But everything went very smoothly, each and every flight arrived a bit early.
We definitely have suffered some climate shock. Curaçao was 30 degrees Celsius (86 Fahrenheit) everyday, but we have yet to see temperatures above 10 C (50 F) here. We even "enjoyed" some sleet one morning (with more predicted later in the week).
But the scenery outside our balcony is still out of this world.
