Thank you for visiting Carnival.com. In regards to your query, the tips
are still done with cash at the end of the cruise. If there is anything
else I can do for you please don't hesitate to ask and thank you for
choosing Carnival Cruise Lines.
I plan on putting the money in envelopes ahead of time so I don't accidently spend it. (I KNOW me! ) Premier gave us individual envelopes the last night of the cruise and that was ten years ago, so I am sure Carnival will do the same.
