I don't speak Spanish and I was planning to go there solo
You'll be fine. Stick to the tourist spots a bit.
P.R. is a great first "international" trip for anyone. Its U.S. lite. A great first step to other Central, South, and Caribbean countries to get you acclimated.
Pick up as much Spanish as you can, at least the basics i.e. direction, streets, locations, things (nouns), a few verbs.
If you have a smartphone, install Google Translate. Download the full app to your phone. That will help a bit.
Install WhatsApp too. That is very popular overseas. You can keep in contact with your foreign friends using that app as well.
