Failed roadtrip trope?

I was watching the "gang hits the road" episode of Always Sunny where they attempt to go to Grand Canyon on a roadtrip, but never get out of Philly due to various issues. This got me thinking about how often sitcoms will have an episode about going on a vacation or roadtrip, only to have something go wrong before or early during the trip, such as missing a flight, car troubles, or something else. Maybe the shows didn't have the money or time to actually shoot off set.

Now, everytime I'm watching a show and the episode makes it seem like they are going on a trip, I just know the odds say that they wont.I tried searching for a trope related to this, but couldn't find one. Am I overlooking it somewhere?

Greetings,

while I don't think we have this trope, we have a forum (Trope Finder) where you can ask such questions.
