Who to tip and whether you should tip extra at all is something passengers seem to all have their own opinion on.

Sometimes, something that’s helpful to one person is a headache to another. That’s the case with an in-cabin safety feature that Carnival Cruise Line has been adding to each of its ships when they enter dry dock for maintenance and updates.

Hiding tiny rubber ducks has become a popular practice on cruise ships. Despite calls to ban it, Carnival hasn't. Their brand is tied to "fun," and ducks align with that.

Although there will always be people who like to complain, this huge change has been met with major approval from the cruise line’s passengers.

There has been an ongoing debate among cruisers when it comes to tipping for years. And to be clear, I’m not trying to take any sides here.
