Yes, we just did this in April at SSR. It was on our reservation already, but I mentioned it again when I checked in. The CM asked what DD9's favorite character is (I had no idea - I would have said Tinkerbelle, but she said Minnie - I asked her discreetly so she wouldn't know why I was asking.) Anyway, on her birthday, they delivered a card signed by Mickey and Minnie along with a 3-balloon bouquet. (Here's a tip - if you arrange for something like this they will attempt to deliver it to your room during the day. If you have the "Do not disturb" sign on your door, they will not deliver it!) I got a phone call later in the day saying they tried to deliver earlier, but couldn't because of the sign - I didn't even know it was on the door!) Anyway, it all worked out because when we heard a knock on the door, DD9 answered it and her face lit up when she saw the balloons.
