[7] Carnival Paradise was built to be the world's first completely non-smoking cruise ship and she was entered into service supported by several anti-smoking and cancer-prevention groups.

Due to poor revenue, Carnival decided to discontinue the smoke-free policy in December 2003, claiming that non-smokers tend to not drink or gamble as much as those accustomed to smoke.

After having skirted the bad weather with minimal inconvenience, Paradise arrived at the Long Beach cruise terminal in the early morning.

[9] In 2018, she underwent a month-long dry dock in Freeport, Bahamas, which added a 14th deck to the front of the ship to accommodate 38 new cabins.

[10] In 2023, Carnival Paradise underwent another refit during her October dry dock which added new spaces as well as upgrades to the vessel.
