Well, if you're asking Detective Pux, I can tell you that cruise ship companies make money by making passengers pay for everything under the sun, and even some things that are over it.

You want a room with a view? That'll be extra. Want to dine at the fancy restaurant on board? Get ready to fork over some cash. How about drinks by the pool? Yup, they charge for those too. And let's not forget the shore excursions and onboard activities that are designed to part you with your hard-earned cash.

Cruise ship companies also make money by charging for everything from photos and souvenirs to internet access and gambling. And let's not forget the retail therapy they offer, with onboard shops selling everything from duty-free alcohol to designer watches.

So, if you're looking for a cheap holiday, a cruise ship may not be the best option. But if you're looking for a floating luxury hotel where you can be nickel-and-dimed at every turn, then sign me up!

In conclusion, cruise ship companies make money by offering a wide range of services and charging for as many of them as they possibly can. It's a classic case of "the more, the merrier" when it comes to their bottom line.
