Is anyone learning Italian because they are going to Italy? I am, and I don't think I will speak very well when I go in three weeks.
Get some inspiration from some Google searches for language learning tips and tricks. The key is consistency. Just a bit everyday. I like to listen to a language learning CD or podcast in the background once a day and do Duolingo as my bare minimum. I also have a blog. Here's a post for what my language learning regime looks like at its best: https://australianoblog.wordpress.com/2017/01/17/how-i-fit-language-learning-into-every-day/

I crammed like crazy before my visit to Naples two months ago. During the 10 days, I used every little bit of my knowledge to the extreme, Words long forgotten somehow came out of my mouth. Sometimes I was just firing single words at people, and using hand gestures. I was communicating, something I was not able to do on previous visits. My experience is that many Italian people really appreciate very bad Italian over none whatsoever. Inversely, they like to take advantage of the opprtunity to speak English with you. Enjoy your trip,
