While the pitter patter of children and babies usually brings joy, often, it’s not so pleasant on the deck of your cruise ship while you’re sunning yourself with a cocktail.

Viking River Cruises has announced a ban on guests below the age of 18 sailing on their vessels on bookings made from August 1, 2018.

The update on the policy says, “As of 1 August 2018, for all NEW bookings, all Viking guests will need to be 18 years old to travel on either the river or ocean product.

Guests booked on a Viking River Cruise prior to 1 August 2018 who are 12 years old or above will be allowed to sail on their currently booked voyage. We will continue to support this program until 2020 when all the previously booked guests will have sailed. For all cruise tours booked after 1 August, 2018 (regardless of departure year), you must be 18 years old on or before the day you are scheduled to embark on the cruise tour.”

But it’s not the first cruise line to create adult-only cruise environments. Here are some of the other cruise lines and ships which are dedicated only to those of the legal drinking age.

Viking Ocean Cruises’ Viking Sea

When the stunning Scandinavian cruise line launched its second ship, the Viking Sea in 2016, the line announced it would be designated as an adults-only ship. The line announced it would be aimed at Baby Boomers and has features which appeal to the age group. The Nordic Spa has features like the Snow Grotto, a steam room as well as a vitality pool. Viking also offers a free excursion in each port to guests, as well as free WiFi, drinks with meals and a mini bar replenished daily. All staterooms have verandas, as well as heated ensuites. There is also a blissful infinity pool off the back of the ship – a pretty amazing holiday if you’re looking for an adults-only cruise.
