@Pelegrin True, it would be hard to live there at any other time!
For those studying Spanish on Duolingo, I highly recommend using the Stories feature if you aren't already. In my opinion, Duolingo Stories are one of the best free language resources available, and they're also the only feature really worth using on the app.
Speaking as a professional translator and all-around language geek, the key to learning a language is not translating sentences or studying grammar rules. It's consuming content in the language that's appropriate for your level, also known as "comprehensible input". Immerse yourself as much as possible in Spanish content, both written content and audiovisual, and eventually you will just know intuitively how things should be said because you've heard them so many times before.
