It occurs to me that this episode is a lot like the old Twilight Zone episode "Stopover in a Quiet Little Town" where a couple wakes up inside a deserted little town and discover everything is like a movie set: the phone is not wired into the wall, the cupboards are empty, the drawers are glued shut, the trees are fake, and the train just goes in a big circle around the town. In the end we discover they have been abducted by giant aliens and placed into a little model town to serve as pets to an alien child. Not one of the best episodes but at least it gave a somewhat more satisfactory explanation for how the couple ended up in this strange town than does this CBSRMT episode. I suspect that "A Holiday Visit" was written by someone who had a little Christmas village and wondered what would happen if you shrunk down and could wander around inside it. The writer obviously was not concerned with the logic of the whole thing, but it's a fantasy so I suppose that is not really important.
