Every cruiseline is different, but Princess has a page on their cruise personalizer online form for special occasion information. If your anniversary falls within a few weeks of the cruise, you give them the date you want to celebrate. Since ours was Aug. 13, and we boarded on the 16th, we gave the 17th as the celebration date. A very nice bottle of wine, complimentary from Princess, was waiting for us in our stateroom with a congratulatory note, and on the 17th the waitstaff authomatically brought us a delicious cake. Could be that Royal Caribbean does something similar.
You were very lucky! We celebrated our 25th anniversary onboard the Crown Princess in July and on our anniversary day we got three balloons hung up outside our door and a mini cake. It was nice - but a bottle of wine would have been even nicer!
