Hello, I'm planning a last-minute 3-day trip to Costa Rica and wanted to ask for itinerary tips. I'm flying into SJO on a Thursday afternoon and flying out at Noon Sunday out of LIR. Given the short amount of time I am in Costa Rica, I am leaning towards renting a car from SJO and try to hit up some "must see" places on my way towards LIR. I am probably going to skip San Jose and try head to Arenal the first day. Any ideas from here? I am in my early 30s and up for adventure, seeing wildlife, and soaking in the culture.
