Jokes apart, this is what I think. If you want to learn conversational Italian to be able to spend some time in Italy, the best way to learn what you need is actually to go to Italy and practice there. Most Italians would love to practice some English with you, and to teach you Italian. You will have a great time. You will have fun. You will remember your holiday when you're older.
PS (however I'm not saying that books or lessons are useless, their importance depends on the kind of language skills you want to acquire)
Just how much did you enjoy the scene of "The IT Crowd" [1] where Jen tries to pull off an act as an Italian/English translator?
[1] S04E04, "Italian for Beginners" - https://youtu.be/csLgX1IHPJs
Jen's fake italian is ok, the "real italian" is cringeworthy: it's like someone who does not know italian reading a google translation, accent is off, grammar is off, word choice is mostly right but also a bit off.
But the scene is still fun, like most of the IT Crowd :)
This is par for the course btw, it's how italian is done in 99% of english content, for obvious reasons.
I'll take you up on it. Do some Italian exclamations have soft versions (that are similar in spelling to each other)? To give English examples, one could say "darn" instead of "damn", or "shoot" instead of "shit".
