Royal Caribbean has stacked two of its strongest family offers into the same booking window, and both close October 5. With Kids Sail Free, an additional guest age 12 or younger sails at no cruise fare when they share a stateroom with two full-fare guests. Separately, 60% off the second guest's cruise fare brings the base of the trip down fast. Kids Sail Free covers select sailings three nights and longer, and the 60%-off second guest applies more broadly — from short Bahamas getaways to week-long Caribbean loops. Taxes, fees, and port charges are extra, and peak holiday weeks — including late November and the Christmas-through-New-Year stretch — are blacked out, so the real sweet spots are fall and non-holiday winter dates.

This is the offer I've been waiting to see before the holidays — for a family of three or four, a free kid's fare plus 60% off the second guest can knock four figures off a balcony week. The catch is those blackout dates, so timing is everything. Tell me your kids' ages and which school breaks you can flex around, and I'll find the sailings where both discounts actually land — then hold a cabin while we compare, because these rates move once October 5 gets close.
