Jacki Free, an IT consultant from Bolton, was preparing to board with her husband, three children and in-laws.
She defended wearing her self-proclaimed Edwardian "Kate Winslet arrival dress".
"If I came wearing 2012 attire people might say I'm being disrespectful. This is a Titanic memorial cruise so it is about putting yourself in that time and era. It's about respecting those we have left behind," she said.
Miles Morgan, the British travel company behind the excursion, has promised an "authentic" and "sympathetic" flavour of Titanic life (without the iceberg-induced interruption).
Food on board is from the original menus of the White Star Line ship, and a Belgian band will play the same selection of music as in 1912.
There will be 10 specialist lectures and two memorial services at the point off Newfoundland, Canada, where the ship collided with an iceberg.
David Holmes, 63, from Taunton, Somerset, works behind the check-out counter at Tesco and has saved for two years for a ticket.
"When I saw it advertised, I just knew I had to go. I know it's not cheap but it'll never happen again."
He insists he's too excited to worry about meeting the same fate as the Titanic.
"I'm far more nervous about arriving in New York by myself - I've never been to America before."
Sarah Haynes, 31, from Stowbridge in the West Midlands, received her tickets as an engagement present.
"I've never sailed before and feel like I could be tempting fate. A few people have asked if it's just morbid curiosity. But I think that's unfair. This is an opportunity to learn about ... history, the value of life and the class system."
Unlike the original voyage, there will be no class divisions on board this time. That doesn't worry Howard Owens, 55, who flew over with his wife from Moreno Valley in California.
"A lot of our friends have lost homes and marriages in the recession. But we can't let that stop us from achieving our goals," he said.
However, he did not approve of those in Edwardian attire.
"Period clothing is an insult to those who [died]. We're here for the right reasons; the presentations, lectures and accumulating knowledge. I'm not here to make a mockery of their death."
Among those on board the MS Balmoral are relatives of victims and survivors of the Titanic, including Philip Littlejohn, the grandson of Alexander Littlejohn, who was a steward in the first-class section of the vessel and survived by rowing away one of the 16 lifeboats on board.
If you're a bit uncomfortable about the direction of disaster tourism, be warned: this is only the start.
Plans are already afoot for an underwater tour of the Titanic wreckage in a Russian-built submarine.
And after that? Owens adds: "We could well do the same thing for 11 September in 90 years' time. In fact we have reservations booked for the 9/11 Memorial at Ground Zero [in New York]. It sounds awful; but it is important to pay respect."
