How much I get card is very dependent on a few things for me -
Disney seems to always card me when I'm solo at the Flower & Garden Booths or Food & Wine Booths. If I am with my husband, we usually are no longer carded (or at least haven't been for the past 4 years).
At the special events - I've never been carded at the Culinary Adventures in Signature Dining, Party of the Senses, 3D Dessert Party or Taste, Shake & Indulge with or without my husband. At the events at the Festival Center - again its dependent on if I'm with my husband or mother or not.
I'm glad they think I have a young face then
At the margarita booth this past February, my friend who is older than me and I were in line to get a drink. She had an older Florida license (pre them adding the Star on it by the ID Number in 2010) and they refused to serve her as they didn't believe it was real. They took my license though and let me by.
Its always better to have it just in case you are someone that gets carded some at home.
