Well, kinda. These people are REALLY unlucky.
Home Alone is one of those movies that presents a conflict that would be so easily resolved in the real world. In the world of Kevin McCallister, however, people don't pick up the phone and the McCallisters apparently have NO ONE who can check on them. Writer John Hughes does a pretty good job, however, of making sure all easy resolutions are ruled out. Here's a breakdown of how Kevin gets stuck "home alone."
The McCallisters are traveling to Paris tomorrow. Kevin's aunt, uncle, and cousin Fuller are joining them, so extra beds are needed. Kevin is asked to sleep with Fuller in the attic.
This will put him far away from his family later.
Kevin is asked to pack his suitcase and presumably does not do so because he doesn't know how.
(This detail can be appreciated later.)
After Kevin shoves his older brother, Buzz, Kevin's dad cleans up the mess he's made, accidentally throwing out Kevin's plane ticket.
This is actually a crucial moment that most people never notice.
