If you are cruising as a couple or single and planning to swim in the adult-only pool on your next Carnival cruise, you may be in for a surprise.

Carnival Cruise Line line is revamping its adult-only pool policies, reports Travel Weekly, senior Editor Tom Seighorst.

Previously, pools in the afts of seven Carnival ships in the “Conquest Class” – Carnival Conquest, Glory, Valor, Liberty, Freedom, Splendor and Victory – were open only to adults. Now they have been transformed into “family-friendly” pools, open for use by all guests, including kids.

Why the change?

According to a spokesperson for the cruise line, many families tend to cruise at this time of year and opening up the once adult-only pools to guests of all ages will help relieve overcrowding.

Where will all the grownups head for relaxation and serenity on sea days?

The recommended alternative is the adult-only Serenity Deck on these ships. However, there are no pools on them so the only water passengers is likely to see there will be the ocean views off the deck.

One person commenting on the Travel Weekly piece lamented, “… adults only pools are MOST needed when there are high volumes of families and children on board.”

In a similar vein, respondents to a Cruise Critic poll on the controversial change voted overwhelmingly (85% of voters) in favor of Carnival retaining the adult-only pool option on these ships.

With this move, Carnival may strengthen its marketing grasp in the family-friendly niche but may lose some travelers over-50 in the process.
