So Nana and Papa wrapped a Disney calendar for each kiddo and wrote "Countdown to Disney" on it. They also gave them a Disneyland brochure with pictures of all of us tapped in it. It was hysterical watching them try to figure out what the gift was. :)
There was even some jumping and hugging when they realized we were all going at the same time and staying in the SAME hotel right next door to each other.
