I know we've had the conversation over carrying original passports or copies before. The most recent news I had seen was that the copy is sufficient.
UNFORTUNATELY...Theory and practice can be horses of different colors. This from the US Embassy website:
Quote:
Americans should always be prepared to present their passports to Costa Rican authorities. A photocopy of the U.S. passport and stamps may not necessarily be accepted as proof of status. In recent months, Americans have been detained, deported or fined due to their failure to demonstrate their legal status in Costa Rica.
