NCL Pizza Anyone?

I was reading an article this morning about Norwegian Cruise Lines and their 24/7 pizza delivery service.  The popular Pizza 24/7 is available currently onboard the Norwegian Epic.  It gives guests the same convenience as you do on land to order Pizza to almost anywhere onboard the ship.
NCL are going to introduce this to the whole of their fleet by the end of August this year.  The 24/7 pizza service goes down well onboard the Norwegian Epic, people can enjoy whether they are playing a game of bowling or watching a film etc.  The pizzas are 16 inch, handmade and stone baked.  NCL charge $5 each for them and are available with a selection of toppings.  You don’t really think of being onboard a cruise ship and having a pizza delivered to you while sat on deck having a drink.  There is so much choice of food onboard NCL I am not sure whether I would pay to have a pizza delivered when I can enjoy so much variety of food across the ship.  It does go down well onboard the Epic but will be interesting to see how it goes down across the other ships in the fleet.  Do you think that this is a good idea?  Would you purchase a pizza onboard?
