Queen Mary 2 -- Staying Ship Shape

* The ship has a large indoor swimming pool in the spa, as well as four outside pools, one of which has a retractable glass roof.

* A planetarium on board—the first at sea—offers a variety of constellation shows and other presentations.

* There are 10 dining venues on board, all featuring ocean views. Recalling the classic dining salons of grand liners of the past, the three-deck-high main dining room—the Britannia restaurant—spans the full width of the ship with a sweeping central staircase, creating a dramatic showcase for those wishing to make the ultimate grand entrance.
