I agree with your son! When we were there for our anniversary last year and I saw that our anniversary was on the TV, I took a picture. Of course, I had to wait for it to go around a couple times to time it right.
I was so excited, I didn't even notice that they spelled DH's name wrong. Did Mickey and Minnie call in sing the "Happy Anniversary" song? They did that too and I loved it. But then, they didn't call this year at WDW. What meal did you have at HH Diner? We went and DH keeps wanting to return for breakfast, but I didn't like it. Fortunately, we've discovered Stacks Pancakes.
