Moin, alle nötigen Informationen bekommt man natürlich von der Reederei, sofern man sich die Mühe macht, dort nachzufragen:
Infants sailing on a cruise must be at least 6 months old as of the first day of the cruise/cruisetour. However, for Transatlantic, Transpacific, select South American cruises/cruisetours and other select cruises/cruisetours, the infant (as of the first day of the cruise/cruisetour) must be at least 12 months old. For the purposes of this policy, any cruise that has 3 or more consecutive days at sea will require infants to be 12 months old on the first day of the cruise/CruiseTour.
Das Mindestalter beträgt 6 Monate, vermutlich höher bei Touren in die Antarktis. Ich würde mein eigenes Baby-Menü mitnehmen.
