While disembarking from Marina on the 18th, I unknowingly dropped my Oceania card case. In it was a $100 bill. When I returned home there was an email from Jose Pila of Guest Relations that it had been found by someone in Housekeeping and turned into the Chief Purser. Subsequently, it was credited to my credit account! The staff of Oceania and Marina are the best! I had not even realized it was missing.
