Gaining

What are your advices on best cruises, cruise ships or lines to gain weight during a pleasant vacation?

Anyone had done that before?

I would like to avoid loud music or too much excursions, just quiet times and relaxation .

I’ve always enjoyed cruising on Norwegian. Freestyle dining so you can eat at any of the restaurants all night. Several places open for all meals. Room service included. I gained like 8lbs on my last cruise.
