Always mention birthdays--and you can have them note this on more than one PS!
At the MK, my DH was wearing a "Today is my birthday!" button that we picked up in town hall and a CM in the Tiki Room gave him a pass to get to the front of the line at any ride we chose.
At the All-Star Music Resort, he got a birthday card from Mickey.
At Teppanyaki, he got a whole birthday cake that we shared with our table.
At Chef Mickey's, he got a birthday cupcake and placemat.
At O'Hana, he got another birthday cupcake and certficate from Mickey.
At the Sci-Fi Drive In, he got a birthday sundae.
At Le Cellier, he got a chocolate "moose."
He was spoiled rotten and loved every minute of it!
