Select sailings worldwide
Age cap 3 & under
Kids free children sharing a cabin with 2 adults (typically 3rd/4th guest)
Where they sleep Kids sleep in your room's existing beds
The catch
Children under 4 sail free sharing a cabin with 2 adults; port taxes and extras (travel insurance, flights, transfers) are still charged; older kids get family-offer discounts that vary by sailing - discounts, not free, so only the under-4 tier is listed.
