San Jose, Costa Rica
This trip should not be done in one day! Too much traveling time for too little sightseeing. The trip includes 4 hours by bus, then 2 hours by boat (can see monkeys and birds on the way) to arrive Tortuguero. Then a good buffet lunch is served, a fast walk in Tortuguero town and another 6 hours of trip back to San Jose.
