Elbow deep in books, loose paper, socks, and crumbs, I clumsily rummage through the gritty depths of my backpack in search of my passport. Dozens of eager travelers shuffle around me, unconcerned by my obvious panic. We are in Miami, Florida in line to board the Carnival Imagination, and I’m the obvious rookie.

I finally retrieve my passport and stand up to take my place with my friends up ahead. Behind me in line, I notice a mountain of a man carrying no luggage at all — not even a crumb-filled backpack. His iron-gray hair is pulled back into a sloppy ponytail. His unbuttoned flannel shirt hangs open to reveal a leathery orange chest. The man stares directly at me with wide, unblinking eyes. I stare back but fail to make eye contact; his stained linen pants and crusty bare feet are far too captivating. “He’s got his shit together,” I think, now horribly self-conscious of my encumbered condition.

Aboard the Imagination, I run into this man on several occasions, and each time he is wearing the exact same outfit. I quickly come to understand that he belongs to an exclusive group of cruise regulars. These natives have cruising down to an art, able to elegantly navigate the ins and outs of the ship and its microcosmic society. They are allowed to do things like not wear real clothes and turn completely unnatural colors. My first day at sea is spent watching this elite class in envy as they move confidently from the shuffleboard courts to the karaoke lounge, from the casino to Xanadu Bar.

As far as I can tell, overnight we literally teleport to Key West, home of the Ernest Hemmingway Museum and lots of feral roosters. The Imagination proves to be a strict mistress, allowing us only three short hours in the town. While ashore, I am surprised at how many fellow cruisers I recognize. I receive several nods and smiles from the very people I felt alienated from just a day before. In hindsight, they probably recognized the scopolamine patch (for sea sickness) behind my ear, the scarlet letter of noobie seafarers, but I like to think that after a day at sea they saw in me the same effortless cool that I so coveted in them. My friends and I cut it close, returning to the ship just in the nick of time, and raised several disapproving eyebrows from the crew. Apparently there are typically one or two landlubbers who get left behind every voyage.

The next day we spend at sea. We speed towards Cozumel, Mexico at a rate that I can only pray allows for adequate iceberg visibility (thanks, Titanic for turning me into an irrational little girl). Despite our breakneck pace, at last I begin to feel my sea legs strengthening. My friends and I spend several hours sunbathing and wandering the ship to see what she has to offer. After winning first place at a pathetically easy game of comedy movie trivia, we observe such activities as a beanbag toss, a hairy chest competition, and an awkward open mic hour. Frankly, these activities fall short of my expectations, but determined to tap into all the fun the Imagination has to offer, we keep exploring.

By dinnertime, little else has proved satisfactory. Luckily, Carnival does dinner much better than it does hairy chests. Between the five of us, my friends and I finish off several plates of food and four bottles of wine. We then make our way to Illusions Disco where we discover that we can purchase alcohol with our room keys. Several piña coladas later, we enjoy a couple of rounds of ill-fated karaoke before retiring to our closet of a room. As I lie in bed wondering whether I am experiencing the gentle swaying of the ship or the spins, I realize I have discovered the secret to cruising.

But why, if cruises offer so much in the way of entertainment, did my ultimate salvation have to come from the bottom of a bottle? At the end of my four days at sea, I realized that it was hardly up to me. Indeed, I was doomed from the start to wind up drunkenly singing the night away with complete strangers. Cruises are meticulously designed to entertain only specific groups of people. I observed four categories: college-aged drunkards, young families, old people, and eccentrics, like my orange friend. I can accept this generalization as cruise law, despite my limited experience, because after four days on the Imagination, I can think of no other type of person that would enjoy cruising.
