2 Years ago we did this on the Freedom. We decorated the door and every day we added more. We had quite a few family members on board and everyone contributed to the daily decorating fun. We also opted to purchase one of the Anniversary decorating packages the ship offers. It's a bit cheezy, but worth it. Our parents really don't go for frills, but when they walked into the room the first day and the room was decorated, they just loved it! Tell your parents congrats!
