All the Carnival cruise ships have a basketball
court. I found it on the last. It was on the very top level near the pool. It was were the bathing suit top optional sign is show. You can't see that deck from the court. I probably scared you. No one on there. I checked. take the stairs to sundeck on the highest level.
Good luck! I can't wait to go again. Ask someone who works on the ship if you can't locate it. Give me a shout if you have anymore questions. email@example.com
