We have been to Italy multiple times and easily survived on "Buongiono, per favore, grazie, ... etc" to be friendly. We have a 1 month trip starting in mid-August.
My wife and I are trying out Duolingo to extend our Italian a little. I know that Duolingo is perhaps not the best conversational choice as I have read that Pimsleur is very good for conversational. But Duolingo is free or low cost and I'm not sure how far I will take this. I have a history of poor language proficiency, poor audio skills it seems. So I don't expect any real level of fluency.
I see that the first lessons deal with being in a cafe, navigating a city, ordering in restaurants. Might be useful. Probably in addition to using Google Translate more of Italian conversation could be at least somewhat familiar to my ear.
If you've done several Italian Duolingo lessons, how did that work out for you in Italy?
