I have managed to find freq flyer tix to costa rica to coincide with my kids winter vacation in feb. It's me, my husband and our twins who will be 6 by then. Here is the question: we would be in costa rica for a week but our inbound flight lands late and our outbound flight leaves early. We would need to sleep around the airport for two of our seven nights. So we have 5 nights and six days left. Is that enough time to go up to arenal area (2 nights) and then down to Manuel Antonio for 3? I am afraid it is a lot of driving for a relatively short time. Ideas or opinions appreciated. Thanks.
