Hello mps69; when you say Golden Princess looks like a shopping trolley, are you referring to Skywalker's Lounge, high above the stern? I do agree it is strange; it's always reminded me of a "spoiler" on the back of a race car. However, a great view from up there. I think it was a good move on Diamond and Sapphire Princess, moving it forward a bit so it dosen't block out the sun at the Terrace Pool.
I have to agree with you on QM2; to me it looks "boxy" and out of proportion--top heavy. The original Queen Mary was a much better looking ship--as is the Queen Victoria.
And I have to go along with Dave and the good Dr. on NCL; and it's a shame because the ships have nice lines; but they've ruined them with what some call "hull art". Hullcrap!
One thing I don't like about the lines of most newer ships is -- the lines -- no curves. If you stand in a hallway of almost any pre-1980's ship, you cant't see either end; there is a nice gently sloping curve. The new ships are straight as arrows from the stern until just before the bow. Oh, I know it maximizes space, but curves are nice. Here is the Dawn Princess--perfectly straight the whole lengeth.
