Soft Opening for shows?

[Ragtime109]

Hello! I was wondering if anyone knows if Tokyo Disney tends to have soft openings or preview performances for new shows. My family is planning a trip July 5-7, but I just read that Disney Sea is opening a new show called Out of Shadowlands on July 9. It sounds really interesting. We could possibly change our Disney dates to the next week, but I already secured a room at Miracosta. If they tend to soft open shows, I figured we might risk it. Thanks for any info!
