Good questions, dsojourn...
I meant to imply the guy running the show doesn't know his star attraction knows how to pick the lock. He may even be clueless what's going on (I accidentally left out a part where Rebecca mentions that Megan looks a lot like her). Also, yeah, the women go missing, and the carnival was the last place they were seen...but carnivals travel, and missing persons reports have to wait, what, 24, 48 hours? Plus they'd be looking for a 5-foot-something woman, not a doll-sized one.
As to the boyfriend thing...she was already mad at him when the story started, and if not for him leaving her hanging she wouldn't be in that predicament. Besides, there's nothing she can do--the curse won't swap back to Rebecca, and she'll be long gone in six months anyway.
But valid questions nonetheless
