First off, there's the position on the ship. As previously mentioned, suites usually occupy prime real estate in the middle of the ship, where you feel the ship's motion the least. Then there's a large (tiled!) bathroom with bathtub (and Gilchrist & Soames toiletries), a partial walk-in closet, a deeper balcony, two TVs, a large couch, a little fresh flower, personalized Cunard stationery, welcome treats, andour favorite parta desk complete with outlet panel for both US and UK plugs.

Since Cunard ships are those that specialize in longer voyages (this 7-day was easy-peasy for the Queen Victoria), you'll probably notice lots of storage space. We (two girls) brought more luggage and stuff on this cruise than we've traveled with in several years, and yet got no where near running out of nooks, crannies and clothing hangers.
We're not cruise novices, so we can say that this was quite the spacious room for a ship, especially the living room portion with the couch. To compare, check out our gallery and video tour of a regular, outside cabin on a Carnival ship, and of course our photo tour of the rest of the Queen Victoria.
Disclosure: We traveled to Norway onboard the Queen Victoria as a guest of Cunard, but all images and opinions are entirely our own.
