Katherine Davenport

Katherine Davenport is one of the main characters and Spencer's little sister. She is portrayed by Dominique Saldaña.

Personality
Katherine Davenport is a young girl who believes in Santa Claus (even though she's afraid of him).

When she is separated from Spencer, she worries about Santa finding her while she's stuck at the lodge with a mean spoiled girl Mary Lynn who braids her hair, gives her a makeover and tries to brush her teeth when the adults are not around.

Later that night, while Mary Lynn is sleeping and snoring loud, she quietly sneaks out and goes down to meet Santa by 4:30 am and gets her hair unbraided and make up removed. Spencer and the four minors then find her sleeping on the couch and Spencer places a doll from the lost luggage room in Katherine's arms before she wakes up.

The next morning, Katherine is reunited with Spencer and is no longer afraid of Santa after the night she had. Her dad Sam arrives on Christmas morning to pick up Spencer and Katherine and Grace, whose parents are out-of-town, is allowed to come home with the Davenports.
