Thanks for that. Is there a container requirement ie Can, bottle, plastic only?

We are going on our second Fred Olsen cruise this summer. Our first was 2 years ago and included free drinks package and gratuities which I assume was to attract back customers after covid. However as we dont drink much alcohol we dont want to spend £50 a day on the drinks package. My question is, are guests allowed to bring on board their own non-alcoholic drinks and water? It seems some other cruise lines allow it but cant find anything for Olsen.
