Costa Rica vs other countries

I was thinking of taking a solo trip to Costa Rica or one of the South American countries.

Is Coasta Rica the place to go? if so what city would be best. I don't speak any Spanish.

other options, Panama, Columbia, Brazil ...

need some help with advice.

Thanks

I don't know about the south American countries or Columbia but Costa Rica is fun.Fly into San Jose and take a car to Jaco. The hotel will arrange it for about $110 each way. First time stay at Hotel Cocal. Good food, casino and more women than you can imagine.
