We have a small flat screen TV with DVD and Cassett players in an "Entertainment Center" in the Salon (see below). While on a cruise we often enjoy watching a movie in the evening (the "Movie Hour"). The girls make popcorn and my daughter will often invite any other kids that happen to be in the anchorage over as well (we've had as many as 10!). Frankly, there is nothing quite so enjoyable as listening to the "girls" laughing away although I personally don't have the patience for it.
I have also found that during a rough passage, letting the girls shelter below and watch a silly movie helps them keep their minds off otherwise worrisome weather.
