As a huge Playstation fan and the father of a Playstation fan, I really suggest not to bring it. First off, depending on the generation you are bringing it is hard to replace if something happens. Having your system break on a cruise is not a fun thing to go though. Second, due to the power they don't even let you bring your own hair dryer. Why do you think they will not stop you from plugging in a Playstation. And just because you can plug it in does not mean you should. Third, and maybe most importantly, it is so much more fun to be away from the Playstation for a bit. My family, maybe like yours, cruise a lot so we love to find out new things to do.
