Considering, too, that the Titanic II is built with a V-shaped hull, particularly in the front, she really isn't designed to do what cruise ships are designed to do, and vice versa.
Actually if you want to get accurate about things, you should consider a vessel's deployment, and not their hull shape, to determine what a ship is. Do you see them building many ships with such an old type of hull these days, still? nope.. you know why? Less effective.
Titanic can hardly have a different design of course, so she will inherit the characteristics that made ocean liners of old unsuitable for cruise work (higher fuel cost, more enclosed decks, deeper draught, smaller cabins for more passengers etc).. but if they would put her on a cruise route from port back to the same port anyway, she'd still immediately be a cruise ship and not a liner anymore... and if they sail her across an ocean from port A to port B, then she's a liner. Even container ships are liners if they sail regularly on shipping routes between ports across an ocean.. A ship does not need passengers to qualify as one. And they have hulls more similar to a cruise ship nowadays than an ocean liner of 100 years ago, I'd say.. so is a container ship then NOT a liner because of it?
Today, the line between ocean liners and cruise ships has become very close together and even one of the last of de dedicated ocean liners, QM2, was deployed for cruise work a lot too and well equipped for it. Of course the old design of the Titanic will make her unsuitable for that in some ways, although things like fuel consumption are not as big a problem anymore with betteer technology, but draught, enclosed decks (shallow ports, tropical heat) and such, still apply.
But it doesn't mean it couldn't be done. It's just a matter of 'where do we sail and what do we do while we're going there?'. Most ships built today are much closer apart, and deployment, not design, is what usually determines their 'job description'. And many cruise ships nowadays sail such great distances and between several ports, regularly, that they can be considered liners I guess.
The way I see it... it's the differene between transportation and tourism, although they do mix.

p.s. on whose people's nerves? I think you're the only one here to be honest.
