We have stayed at Value, Mods, and the Poly. My DD got a card from Mickey and Minnie for her birthday (Value and Mod), we got roses and card when we got married at Sunset Point (Value and Deluxe resort) and last year when we stayed at the Poly LV Conceirge for our anniversary and DD birthday we had cake for her birthday and balloons with a card, and strawberries with champagne for our anniversary.
However, we go 3-4 times a year and on SEVERAL occasions have had no acknowledgement of special events. It is a nice surprise when and if it happens, so I never count on it.
If we really want some "acknowledgement", I always book a character meal for DD birthday and then she gets her cake/cupcake and card and isn't disappointed. We don't always book a special meal for our anniversary but when we have, we have received a card or dessert.....
Otherwise, we just LIVE to be there and if I was a zillionaire, I would live there!!!
