Does my mother's Second Childhood count? She watches "Oliver!" about three times a day, although it's sliding over to "Jesus Christ Superstar" (once a day so far, but sometimes twice).
I don't have kids- but I baby sit my sister in-laws little girl and we watch the little mermaid almost every day sometimes twice a day. She likes repetition! xD
Mine don't do this any more, but when they were younger, they could watch the same movie over and over for weeks on end. The Road To Eldorado was probably the most popular in our house - I probably still know the whole thing by heart.
