Last fall, they weren't doing anything extra beyond the usual -- you stop at guest services on the way into any of the parks; they give you a button to wear, and then you get wished happy birthday a lot. You might be lucky and get a pin or two from a CM along the way. She can wear the button every day, if you want to do that. It's always helpful to be outgoing and "chat up" the CMs at rides, etc. Sometimes they have "perks" to give out.
