If this is interesting to you, there's still one ocean liner left: https://en.wikipedia.org/wiki/Queen_Mary_2
Buy a ticket while you can.
I wonder if Cunard/Carnival will ever build a replacement to her.
I had a coworker whose not a fan of flying who has done a couple crossings now, really enjoys it! I think of the Queen Mary 2 a bunch because of them, their tales. A little world of fans who really enjoy doing the crossing.
Are there plans to scrap it anytime soon? It's modern, built in the early 2000s, and seems in some ways more like a modern cruise ship than an ocean liner of the last century.
Definitely can't afford that, this is going to be one of those life regrets I think that I won't be able to do.
