Earlier quoted context omitted.
Not GP, but I moved to Costa Rica for a few months in 2013. Depending where you go, you can get away with very little to no English. I was in a (tiny) surfing town, Playa Grande. It gets a lot of foreign surfers, and so all the locals speak English. Many ex-pats live there year-round. Nearby is Tamarindo, very similar there, and a much bigger town. I can order food and ask for directions and have basic conversations…
I suppose you mean you can get away with little to no Spanish, so English is OK?
I would not be afraid to return if I was forbidden to speak Spanish.
