We are celebrating my birthday and my step sons college graduation while sailing. Should we note that on our file? What is the benefit of doing so?
You are more then welcome to note this on your account but in all honesty I'm not sure it does anything. You might get special recognition or you might not it is hard to say.
Sometimes the main dining room staff will bring you a dessert to celebrate birthday's especially if you let your head waiter know when you meet him or her on board.
Royal does offer options for purchase if you want to go that route as well. you can buy room decorations, cakes, cupcakes. The cakes and cupcakes can be delivered to the room or to the dining room.
Happy Early Birthday to you and Congrats on graduating from college to your step-son.
