Is a Six Flags Flash-Pass worth it on June 2 (Thursday)?

I'm planning on taking my cousins who are visiting to Six Flags tomorrow. Just wondering if the Flash Pass is a good idea or not since it's quite pricey. During peak summer it'd be a no brainer, but it's still really early. Tomorrow is a weekday and most schools aren't out yet (colleges are). Do you think it'll be worth the extra $$? Thanks.
