As an avid traveler, I pride myself on my sense of being in the moment with each new journey and destination. Yet the second my camera, the proof of "how much fun I was having" was lost, I became inconsolable. It forced the unpleasant question of the motivation behind my travel.
Plenty of things can go wrong on a cruise vacation. You could get seasick, or sleep through breakfast, or lose at blackjack, or puke over the rail, or god forbid be on a cruise ship that's lost power and drifting out to sea.
