The ONE thing I would LOVE to see in the next installation/update of the Titanic model, is the Grand Staircase, and first class reception on D-deck. And also a way to get into the wheel house on the bridge.
And also the palm court, whichever area the sign on the door said was opening soon.
But, I know not to ask too much of the devs, there's much else to ship sim than Titanic! (but Titanic is still important
)
