Stavo sfogliando il Catalogo Carnival Australia (hanno Spirit e Legend basate lì, è quasi come se fosse una compagnia a sé) e arrivato verso le ultime pagine leggo questo:

Stateroom Age Requirements:
To ensure there is suitable supervision, there needs to be at least one guest 18 years or older in each stateroom. However, to accommodate families cruising together, children may occupy a separate stateroom to their parent/legal guardian, providing one child is 16 years or over.

Dico: "Bello! Finalmente una compagnia che opera in Oceania che permette ai 18enni di partire in crociera da soli!"

Poi scendo giù e leggo:

Minimum Age to Book:
For cruises departing from an Australian port between 1 November and 7 January, any passenger under 19 years of age on the day they board the cruise, must travel in the same stateroom as a responsible adult 19 years or older. In addition, from 8 January to 31 January, there is a limit on the number of passengers under 19 years of age who can travel unaccompanied. Once the limit is reached, a responsible adult 19 years or older must travel in the same stateroom. We can advise you at the time of booking whether the limit applies to your booking. The responsible adult is accountable for passengers under 19 years of age in their stateroom for the duration of the cruise, and the ‘Rights of the Captain’ will be applied to anyone who displays disruptive behaviour.

Ma lo fanno apposta Nel periodo in cui posso partire io (vacanze invernali) per la legge australiana ci vuole un'anno in più... Ma cosa cambia
