Costa Rica. I've already been and it was an incredible experience. I cannot wait to go back. The people are so friendly and nice and completely understanding of my broken Spanish. It's beautiful in its naturalness.
Having a layover at the glass-windowed airport in Costa Rica on the way to and from Peru is SUCH a tease. It's the most beautiful place I have ever seen in my life. I hope to go back and spend a few weeks in the future.
