Over the past few decades, cruise ships have become more diverse in the activities, restaurants, itineraries, and accommodations offered. This diversity has caused the industry to boom, becoming one that generates multiple billions of dollars.

Over 27 million people enjoy cruises annually. We outline the best cruise lines for adults, both adults-only and those with adult amenities.

Cruises With No Kids (Adult Only)

Adult-only cruises are an emerging category within the cruise ship industry. As the name suggests, these are cruises geared only towards adults.

This trend resulted from the increasing popularity of adult-only areas scattered aboard ships. Many cruise lines took note of this and began offering cruises geared toward adult entertainment and activities.

These cruises are either adult-only, meaning there are no kids allowed, or they do not have child-friendly activities, which deters families from selecting them. The key to finding the best cruise line for adults is to look for ones without children’s facilities or with a focus on food, history, and culture. 

U by Uniworld

U by Uniworld changed age restrictions in 2018 for the river cruises they offer in Europe. Originally, this cruise line was intended for millennials. The company still focuses on young adults in its marketing and branding, making them stand out over other lines.

Itineraries have cultural programs, social events, and immersive activities. They perfectly cater to a millennial lifestyle where experience ranks higher over materialism. U by Uniworld offers cruises in Germany, the Netherlands, Austria, Hungary, and Slovakia. Guests can enjoy bike rides along the countryside, cocktail workshops, kayaking, and walking tours. 

Some of this cruise ship’s itineraries are unique, ranging from tent camping on the rooftop of the ship, to top deck wine and painting, to silent disco parties. 

Virgin Voyages

Virgin Voyages launched in 2020 with a fully adults-only cruise. To go on board any of its ships, passengers must be over 18.

Itineraries generally focus on food, culture, and onshore activities, making them ideal for a longer and more sophisticated type of cruise. Instead of non-stop entertainment and continually open buffets, passengers can relax between ports. With a Viking cruise, passengers can expect a cruise completely designed to immerse them in the destination.

Activities include wines guided using a sommelier, guest lectures, and cooking classes. They also have opportunities for relaxation with various spas, baths, and pools. 

Cruises with Adult Amenities

Azamara Cruises

Final Thoughts

Adults need to recharge, too! Enjoy some alone time with these best cruise lines for adults. While there are several geared to adults, some offer children’s services as well. 

With this niche gaining popularity, many cruise lines have either categorized these cruises as adults only or have discouraged families from attending. By eliminating or scaling back services for children, the cruises are less appealing for families as they will have to tend to their kids.
