Everything at Disney. The parade, the snow, the fireworks and lightshow at the castle, the characters, the boys meeting the characters, the boys faces throughout the whole 3 days.
We were soooo lucky that it didn't rain once and although it was cold and frosty it wasn't too awful and unbearable. I did dig out my thick grey coat to wear though which helped.
I put this on the computer the day after we came back and the boys immediately started dancing shouting "Disneyland!! Disneyland!!" and I cried when I heard it. I now just need to learn the words.
