I have watched "A Night To Remember" and appreciate it's historical accuracy, which is why it's such a shame they got the break up wrong.
I think that you should watch "Legend Of The Titanic". Now, please understand I don't recommend this for its accuracy, of which it has none. "Legend Of The Titanic" is undoubtedly the worst and dumbest movie I have ever had to lay my eyes upon. Its stupidity is unmatched and is good to laugh at. I don't want to spoil too much, but just as a taste, everyone on board is saved by a dog-faced talking octopus.
BTW, my personal favorite Titanic movie is James Cameron's. I know it's not quite as accurate as "A Night To Remember", and the romance aspects aren't the greatest, but you have to admit the movie looks incredible
