Hi. My DS had his 4th birthday during our trip this June. We went to MK on the day, made our first stop at City Hall where he got his birthday pin, and a call from Goofy wishing him a happy birthday!!!
All day CM's and other tourists wished him a happy birthday.
We had a PS at the Crystal Palace for lunch, where he got a card signed by Pooh and friends, and a cup cake with a candle.
All the characters made a fuss over him, asked him how old he was, etc.
He was so made up that for the rest of the holiday he kept asking to to wear the pin!!! (which we wouldn't let him!!!!)
