USA Today's Cruise Blog recently reported on the fact that Princess Cruises is adding 300-square-foot screens on the top decks of seven more of its Princess ships over the next three years (it already has the screens on the top decks of seven ships already). The giant LED screens can show movies day and night as well as broadcasting sporting events such as the Super Bowl and concerts and plans to broadcast an exclusive-to-the-cruise-industry concert by top-selling recording artist Josh Groban. Personally I'm no fan of the giant screens but some of the hard-core cruisers seem to really like them. Other lines including MSC Cruises and Carnival Cruises offer movie screens on deck on some of their ships.
