Cruises are the best vacations for introverted travelers. Here's how I make them work for me.

It's important to choose a cruise line that fits your travel personality.

Since my family knows me and my son are introverts, we choose cruise ships that attract a more calm clientele and offer a more elevated experience.

I've sailed with a few lines, but my family often chooses Princess Cruises because its ships are a bit calmer and more elevated than those packed with water slides and rock-climbing walls.

Plus, the more attractions and activities a ship offers, the more likely the people on it are seeking a louder, wilder time.

I've found the two times when a ship's decks are virtually empty are early in the morning and late in the evening.

For most of the day, the busy main pool decks of the Caribbean Princess were full of revelers enjoying the spring-break sunshine, but in the morning and evening, things were much quieter.

Not having to fight the crowds to get a chair on the pool deck makes for a relaxing time of watching the ocean or reading a book quietly.

Each morning on a cruise, I set an alarm for 7 a.m. and wake up before my family to go for a walk around the ship.

The Caribbean Princess had a jogging track on one of the lower decks, and walking there while taking in sweeping ocean views was a beautiful way to start my days and burn off the stress caused by being around other people.

Although our ship offered a fitness center and group fitness classes, I found the peaceful outdoor track to be the better option for my introverted self.

Morning routines truly are an introvert's key to powering up for long days of cruising, whether those days include time in the pool or adventures in various ports of call.

After my morning walks, I'd grab a coffee and head to one of the ship's upper decks, where I'd read for a bit, getting caffeinated and ready for whatever each day would bring.

My most recent sailing included three days at sea, meaning we did not get off at a port for about 72 hours straight.

On sea days, the ship's main areas are way more crowded, so I always book a spa treatment to escape.

On my recent trip, I booked a seaweed wrap and massage and spent time before and after the 90-minute service relaxing in the spa area, sipping infused water, and reading in my cozy robe.

Another day-at-sea tip for introverts is to take advantage of the ship's adults-only areas.

Even if you're traveling with children, it's perfectly acceptable to send them off to the kids' clubs on board while you relax in a much quieter atmosphere.

The Caribbean Princess had an adults-only pool area available to all guests. Still, we took our seclusion a step further by renting a cabana in The Sanctuary, the cruise line's exclusive deck area just for grown-ups.

There, I recharged in complete silence by reading in a pool lounger overlooking the ocean.

On one night of every cruise, I take myself on a little date, sending my husband and kids off to explore the ship together while I have dinner on my own.

I curl up in my chair with a good book and eat my dinner peacefully while I allow my body to relax and unwind from a full day of activities.

With no one at my table to chat with, I have time to recharge and quiet any stresses I've felt throughout the day.

On my sailing aboard the Caribbean Princess, I treated myself to dinner and a show.

Since the cruise line offered performances nightly in its onboard theater, I was able to head there after dinner to watch a show in darkness and solitude.

Yes, there were hundreds of other guests in the audience, but since I wasn't with my travel party, I didn't need to make small talk with anyone and was able to soak in the relaxing vibes.

Another way I take some time for myself while cruising is to choose a few activities on the ship's entertainment schedule each day to attend alone.

From a paper-flower-making class to cooking demonstrations, our ship had plenty of interesting activities on offer each day.

Among my favorites? Sitting in on a trivia or game show-style activity all by myself — a team of one, ready to use my brain only for thinking of answers, not for making small talk.

I'd be remiss if I didn't mention the bliss of a cruise-ship nap, which I took full advantage of most afternoons and reaped the benefits of.

After all, there's nothing quite like being rocked to sleep by the ocean at 3 p.m. after a long day in the sunshine.
