Have a wonderful time and be sure to take lots of pictures! My best friend and her husband and kids go almost every year, and she has some adorable pictures of her little girl, with that look of wide-eyed wonder.
This is a story about the Disneyland in California, but my favorite Disney story takes place when I was 12 and went there for the first time. My little cousin cousin, Amanda, lived in California at the time. I was 12, she was four, and although she had been there before, her being four years old for this visit made it prime time perfect, as far as her enjoyment. We had a super fun day there, and towards the end of the day, my mom and I took her on the "It's A Small World" ride, with all the singing dolls representing different lands. The best part of the ride was the look on Amanda's little face. She had big blue eyes as it was, but on that ride, her eyes grew to the size of dinner plates, and she was completely in the moment, trying to take it all in. It was the most adorable thing ever, and we all still talk about it. She passed away not long ago, and that remains one of my fondest Amanda memories.
