One of the most popular group types and with good reason. Friends old and new come together from all over America — and sometimes from even farther away — for one unforgettable vacation voyage. Neighbors get better acquainted and build a stronger sense of hometown community by sharing a common (yet extraordinary!) experience.

Because today's superliners offer a huge array of fun activities for all ages and lifestyles, cruise vacations are the perfect fit for any family reunion. Your kin won't hesitate to travel great distances for such a truly special event, a group vacation that actually succeeds in keeping everyone happy. And your floating mega resort and exciting itinerary will offer enough flexibility to enjoy a refreshing balance of time together and time spent in smaller groups. Plus, it's the best value in travel for groups — the most affordable, convenient, and fun for the whole crew.

Children can enjoy their very own vacation experience thanks to supervised kids' clubs that offer more unique adventures — onboard and ashore — than any camp could back home. Many ships also offer special clubs and activities for teenagers, from teen discos and pools to coffeehouses and video arcades. Adults will find endless possibilities, from Broadway-style shows and relaxing spa services to casino gaming and a variety of enrichment classes at sea. And, of course, everyone can enjoy a variety of shore excursions in port!

Dining onboard is a dream come true for big families. Enjoy premium cuisine with flexible dining hours and seating options. From American and Italian favorites to steakhouse and sushi, it's a culinary cornucopia with something for everyone. Go casual with sumptuous buffets, or relish more elegant settings at a myriad of gourmet eateries and themed lounges. Some ships even offer 24-hour pizzerias and ice cream bars. And perhaps the best part about dining on a family reunion cruise? Nobody has to rinse the dishes after eating!

Make the biggest day of your life even more special by hosting your wedding in the luxury and grandeur of a cruise ship. Cherish the spectacular panoramic views of the ocean and let the crew pamper you with service fit for a king and queen. And a wedding at sea couldn't be more convenient — there's no need to hire a caterer or photographer. While it's often difficult to reserve enough hotel rooms for your wedding guests, many superliners boast nearly 1,000 staterooms, so getting everyone together is easy. Plus, it's like getting a honeymoon for free — you're already on a romantic vacation to exotic destinations!

Religious groups find peace and harmony on the open ocean. Church and temple outings at sea are ideal for all ages, offering a healthy balance of fun and time for spiritual reflection in the great outdoors. And a place designated for worship can be found on most cruise ships. It's a wonderful opportunity to bolster the bonds of your religious community and broaden horizons through exploring different cultures around our world.

Please note: some religious groups may feel more comfortable on select cruise lines — certain fleets offer a more relaxed atmosphere.

Upgrade your plans for graduation or your class reunion! Trust us, the R.S.V.P. acceptance rate is nearly 100% for a cruise graduation party or reunion — no matter what your classmates thought of the school or how long ago you graduated. There's no better reward for all of the hard work towards a high school or college diploma than a celebration at sea. The backyard barbeque just can't compare and a cruise is more affordable than a land-based resort vacation.

For reunions, today's modern mega ships provide the ideal setting to share stories with old classmates, whether you are recent graduates, alumni with young children, or it's your 50-year reunion. It's also an incredible environment for networking. And the great variety of entertainment onboard and ashore means everyone will have a blast.

Unite your former service mates or treat your local veterans' community to the voyage of a lifetime. Give the ultimate "thank you" for the priceless service and courage that U.S. military veterans have shown for our country. It's the perfect way to catch up with each other and build a stronger community with new and exciting travel experiences.

Whether you're part of a book club or a sports team, everyone in your group is sure to have the time of their lives with a cruise vacation. What better way to preserve the ties between members for years to come than by traveling to exciting destinations together? Whatever your group's interest, you're sure to find it onboard.
