· Not all airports have free WiFi (she's totally spoiled by JetBlue's Terminal 5 at JFK).
· Not all airplanes have seatback TV screens with satellite programming (again, spoiled by JetBlue).
· Flight attendants generally don't care about: in which bin you stow your carryon; the fact you're vegetarian unless you've ordered a special meal in advance; that you really have to pee while we're on an active runway; that the onboard coffee sucks.
· Speaking a little more quietly, more reverently than the usual loud, affable American volume can make all the difference.
· Airports are big. Big airports don't necessarily have golfcarts, or even moving walkways, to get you from gate to gate.
· Cruise ships are massive. They are like floating skyscrapers and yes, over 3,000 people regularly fit in just one. It's crazy, I know.
· International Starbucks often offer different things, both drinks- and pastry-wise, but they will always have WiFi!
· There's no way to switch TV programming between languages. The shows are either dubbed or subtitled or in one language, and that's that.
· Jet lag is a very real thing. Drinking lots of water is definitely the best way to help beat it, as everyone says.
Note: all this was only after two days. Check out Part 2 for the rest of the trip.
