I've sailed alone on 4 different cruise lines. Here are my top 5 tips for taking a solo cruise.

As a result, my trips have either been paid for or discounted by the cruise lines.

But I always try to find time for myself. After all, there's nothing better than some alone time with unfettered views of the ocean.

And on some trips, I've left feeling socially fulfilled despite going alone. Here's how ... 

If you feel anxious or insecure eating alone at a restaurant, odds are you might feel that way for the first few days of the cruise.

It could be daunting at first. But past this anxiety, cruising alone provides a great opportunity to make new friends. If you're there to mingle, head to the bars, pools, or even mini golf courses.

Port days and the opportunity to explore new destinations are exciting.

But if your priority is having the ship's amenities to yourself, it's also one of the best days to stay put.

The lounges, buffets, pools, and popular onboard amenities will be nearly empty during these days. So if you want to lounge by a quiet pool with a book and no screaming children in sight, consider spending your port day on the vessel (or at least heading back early).

This tip applies to cruisers traveling in groups as well. If you cruise to eat, prioritize booking the specialty restaurants you care about. The sooner you do, the more likely you are to secure your top restaurants and dining times.

During my two-night media sailing on Royal Caribbean's Wonder of the Seas, the nighttime comedy shows were almost completely booked by the time I boarded the ship.

The more proactive you are, the more likely you'll catch the shows you want to see.

To make the most of your trip, book a cruise line that's compatible with your interests. Do your research: Different cruise lines target different demographics.

Instead, opt for the adults-only Virgin Voyages or the Gen X-approved Celebrity Cruises.

Some companies will charge an additional "single supplement" for solo travelers booking a stateroom designed for more than one guest.

On cruise lines like Silversea, the supplement starts at an additional 25% on top of the base fare. On Royal Caribbean, it could be double the cost of your trip.

Instead of paying this hefty add-on, see if the cruise line has cabins designed for solo travelers. Companies like Celebrity and Oceania offer this.

Yes, they can be small. But you could be end up saving a significant lump of cash by opting for these solo cabins.

Bring a book, grab a drink, and head to an observation lounge. Enjoy the comforts of alone time. It'll certainly be more entertaining on a cruise ship than sitting alone at home.
