Cruise ships might come in different shapes and sizes, but all lines share one common goal when it comes to cruising: having fun.
With a wide array of activities onboard -- from dancing and deck parties, to game shows and water slides -- having fun on a cruise ship is easy. Still, some passengers go above and beyond in their quest for fun on a cruise, seizing all the amusement to be had at sea.
Here are 10 people who nailed cruise ship fun, and made the most out of their vacations.
