Deal watch: Crystal Cruises launches 'kids free' offer
Crystal Cruises has kicked off a "kids sail free" offer for more than a dozen sailings between September and December.
Under the terms of the promotion, a single child age 17 and under can sail for free when sharing a cabin with two adults.
Sailings available with the offer range from seven to 15 days and are in the Mediterranean, South America, Caribbean and the Canada/New England region on both Crystal ships, the Crystal Serenity and Crystal Symphony.
The line's Crystal Family Memories program also offers additional shipboard credits of up to $400 per cabin and other perks for groups of six or more.
Fares for voyages included in the new kids promotion start at $1,875 per person if booked by April 30.
The Crystal Symphony recently emerged from a major makeover. For a look inside the revamped ship, click through the carousel below.
