Hi there, great to hear you feel comfortable after just 2 levels! The language used in both Brasil and Portugal follows the same grammatical rules, and the vocabulary is also essentially the same. Brasil is huge though, and there are a few variants in words or structures sometimes, yet nothing that will prevent you from understanding or being understood for the most part. The one big difference that I need to mention is the pronunciation. If you are not used to the Portuguese pronunciation and just to the Brazilian one, you might be surprised, because it's quite different. In Portugal people tend to speak a lot faster, and words seem to be shorter than in Brazilian Portuguese, so my advice would be to listen to some videos in Portuguese from Portugal before your trip, just to get your ear a little more trained. In my experience traveling there, it was a bit hard understanding during the first days, so I often asked to repeat slower, and then it got easier and easier. People usually understood me perfectly, but said I had a Brazilian accent!! In any case I loved the country and the people too, so enjoy your stay there!
