I am not sure about the suitcase disembaration thing, this may no longer be true. I was in a sky suite aboard the galaxy last week and we had to put our cases out by midnight, like everyone else. Then to top it off, they misplaced my suitcase, it took an extra 35 minutes to find it (it was in the furthest section away from the section it was supposed to be in, red tag still firmly in place on the bag).
I did enjoy the in suite dining especially for breakfast, and also for some dinners. Our butler was attentive and very professional, and was helpful in cases where I had difficulty with other parts of the ship's staff.
