Snow, snow, snow!

The following quote is from one of Little Sister and Big Sister's most favorite Christmas movies. Can you identify the movie it's from? If so, you might very well be a long lost kindred spirit of ours.

"We're booked for the holidays."
"Vermont, huh?"
"Oh, Vermont should be beautiful this time of year, with all that snow."
"Yeah, you know something... Vermont should be beautiful this time of year, with all that snow.
"That's what I just said."
"We seem to be getting a little mixed up."
"Maybe it's the music."
"Maybe it isn't only the music."
