Costa Rica Pre-Thoughts

So i am about to go to Central America this summer to the great country of Costa Rica. I have been all around Europe, Mexico, and the US but never down south to Costa Rica or anything like it. I am excited and ready to head to a brand new ec0-system and culture. I want to see the rain forest and the business culture in Costa Rica. The volcanoes seem very interesting and I look forward to being in the high mountains and especially on the beach. I plan on spending maximum time on the beach.
