That's not the point, the entire point is reenactment. This ship isn't supposed to offer the same comfort and security as modern cruise ships, because it's not a cruise ship in the first place.
Soooo, even less to do then, yeah, no thanks.
Comfort and security on a modern ship... Have you not seen how many ships have limped back to port with a full load of passengers sick from something that spread throughout the boat? The last one, the passengers shut down the toilet system as well. You won't get me on a modern ship today, probably come back with Zika or something.
Oh, and as for modern being safer..
In ship design you have a choice, less wobbly (less seasickness) but unable to recover, or more tippy (more seasickness), but able to right itself. Care to guess what new cruise ships use? One good rogue wave, and a modern ship will be on it's side in 2 seconds flat. As they make bigger and more stable ships, the odds actually increase of this happening.
The Point of this is not security, its the magic behind such thing, and there cannot be magic when there is security. Do you know why there weren't enough life boats in the first place? The number of life boats was very much sufficing in compliance with maritime safety regulations of the time, since the amount of lifeboats was not determinate by the number of passengers, but the weight of the ship (they had been intended to regulate vessels of only up to 10,000 tons).
Magic?
Above deck was glamorous, below deck was a normal ship of the day.
Unless you had a first class cabin, you were below deck (think 1 star hotel, worse for steerage class), which is far from magic. Only the wealthy were up on deck and in the ball room. It's not a modern cruise ship where everyone dines in the dining room with the captain, even in the movie, Jack only dines up there because he snuck up there (which would have been difficult or impossible). Worse though, when they hit the iceberg, the crew locked the stairwells down to the lower decks so that the lower classes would stay below and remained that way so that the wealthy could get the lifeboats. Most of the people who died never even managed to get up on the deck despite plenty of time to do so.
Be careful glamorizing the past as it's usually only the tales of the wealthy that get told.
Also the titanic did not use "bad metals', is was build of "thousands of one inch-thick mild steel plates and two million steel and wrought iron rivets and equipped with the latest technology at the time."
"However, slow bend testing, a more likely applicable strain rate, of four hull plate samples showed average toughness of 55 MPa-m1/2 at 0°C, quite reasonable for this application."

Even if the rivets where bad, this was more then unlikely the cause if it sinking.And keep in mind we are still talking about tests with 100 year old parts of metal from the bottom of the ocean.
Like every major disaster it's almost always a series of events or failures, in Titanic... The life boats are well known.
Less known is that the binoculars for the watch who were looking for icebergs were locked in a locker, the only person with keys was left behind in England due to a last minute crew change. Without binoculars, they couldn't spot the iceberg soon enough. They were repeatedly warned of icebergs in the area, and despite no binoculars they sped on and at those speeds, they never had a chance to avoid it. They were so arrogant, they turned off the radio after getting annoyed by all of the iceberg warnings.
Titanic would probably have survived had White Star used the original design, it was
almost unsinkable, it's how modern ships are designed today. The designer had the right idea, he was just too far ahead of his time for them to understand it (White Star was also almost broke). White Star had trimmed the bulkheads down to save costs, this was what allowed water to spill over from one compartment into another, ultimately sinking the ship. Had they remained full height, the ship probably would not have sunk, but even if it had, it would have taken much, much longer. Not only would nearby ships have reached them in time, but more than likely it would have made it back to port on it's own.
Going back to the metal, the metal for the rivets was not great, even for the time. However, a hull is under compression, so no, the metal didn't sink it. Had they not hit the iceberg, the hull would have survived for decades, as proven by the Olympic. However, when the hull was hit, it did allow it to open a larger gash than it should have. Causing a faster sink rate, and water to go over the bulkheads. The rivets played a role in the sinking, but they didn't sink it.
Change anything in that chain of events and Titanic would have survived.
Binoculars or simply slowing down would have allowed them to avoid the iceberg, or at least lessen the damage.
Better metals would have reduced the sink rate and damage.
Proper design would have slowed or eliminated the sinking.
A better trained crew could have gotten more people into the life boats.
More lifeboats would have saved more people.
The whole thing was a sh*t show from start to finish.
