One advantage of cruising to ports of distinctly foreign cultures is the opportunity to stretch your comfort zone, the level at which you function with ease and familiarity.
The result is that you can experience both worlds — soft adventures of exploration off the ship during the day, then basic vacation necessities, such as a fine meal and a comfy bed, back onboard for the evening.
All of the above came into play during a recent cruise in Southeast Asia, where I walked in the woods of Borneo with a headhunter, unintentionally insulted the Sultan of Brunei, and ceremoniously crossed the Equator at sea.
