YA or Fantasy, people working in a theater, under stage leads to another realm, too many trips they'll be stuck there.

I'm looking for this for my sister-in-law, who can't remember the book other than a few details. It's probably about 10-15 years old, and she thinks it was YA, but isn't sure. The main character was female. Not an actress, but liked working on the play and hung out with other people connected to the play and in the theater. My SIL doesn't recall that everyone traveled to the other realm, only a few people could do it, and most didn't even know it was happening. Possibly, the other realm was going back in time, but not sure. Once there, the people had to figure out a way back, and when they did, they could cross back and forth, but not infinitely. I think, they had to prevent some sort of evil from following them back and ruining the play (I may be mis-remembering what my SIL told me). But if anyone can come up with possible books, I'd be so grateful! I want to get the book for my SIL again (and read it myself), but I have come up empty handed with every search I've tried.

Possibly Saving Hamlet?

Here's a review:
Fans of the Bard will relish this evocative and witty time-travel tale that has student stage manager Emma falling through a trapdoor into Shakespeare’s 17th-century Globe Theater , where the high school sophomore is mistaken for a male backstage assistant. Before Emma has a chance to adjust to the language, conventions, and stench of Elizabethan thespians, she is swept into the frenzied preparations for the premiere production of Hamlet, the same play being rehearsed at her school under the questionable leadership of a new student director. Using the trapdoor as a portal between two centuries, Emma begins leading a double life, finding crises, triumphs, and romance in both worlds. First-time author Booth captures the thrills of the theater in two eras while providing an striking portrait of Shakespeare and the Chamberlain’s Men through Emma’s eyes. Her energetic narrative encapsulates general issues of Elizabethan England (disease, pollution, hygiene) and personal ones confronting Emma in modern times (earning respect from her cast, rebuilding broken friendships, and saving a show from potential disaster). As enlightening as it is enjoyable, this whimsical novel deserves applause of its own.

No, she said that sounds somewhat similar, but she thinks the other realm was darker, more fantasy/demon type place. Thanks for the suggestion, though, this one sounds good too!
