Can I get by in Brazil with just English/Spanish?

Years ago, I went to Medellin with just basic Spanish. I did okay, and learned over time.

Now I'm curious about Brazil but don't know any real Portuguese. I'd slowly learn over time but am not in the mood to just lock myself in room and study hardcore for 1 month.

So I'd likely arrive without much language skill.

Would this be okay in a large city like Sao Paulo? Or it's just asking for a bad time?
