On our first day in London, we stopped by Leicester Square in the morning to get tickets for the whole family to see Wicked that night. 
We were trying to decide if we should all go -- if Mallory was going to be too young for it or if she would fall asleep. Despite the fact that she isn't in this photo, she did go with us, and she loved it - singing, dancing, costumes, and a witch that looks like a princess.
