Jill Shropshire turned the key in the lock and immediately felt a snap. She stood for a moment in disbelief: the key had broken off in her hand.

“I wasn’t looking at what I was doing, and I just shoved it in there … I think I put it in upside down and broke it off in the lock,” Jill tells CNN Travel today. “I’m immediately like, ‘Oh no. This is not good.’”

Jill turned around to show the broken key to her sister Jan Shropshire. But Jan had already clambered into one of the twin beds, kicking off her boots.

“I was drunk,” Jan tells CNN Travel. “I was crawling to bed already.”

Jill got Jan’s attention by waving the broken key.
