This may have been talked about, sorry if it has. I just go one time a year and do fast pass to make it through all houses and a few a couple times. Is the consensus that Scream early will shorten/extend/or have no effect on later lines.
Are you asking if the earlier Scream Early times this year will result in shorter lines compared to last year?
I detail my speculation on this
topic here. It may have been discussed elsewhere in this thread as well.
To be clear, I think the earlier times
will shorten line times later, but the amount may be negligible.
Potentially more importantly... If you're doing single day Express, the assumption is because they're not selling multi day Express, the Express will have shorter lines compared to last year. (As a result, the regular line may also have shortened lines.)
This all may be a drop in the bucket compared to other factors, like overall attendance or weather this year vs last.
A few weeks into the event, we'll start seeing comparisons of this year vs last on line times. Then we'll get plenty of overconfident statements (on this forum and elsewhere) claiming X or Y or Z was the big factor in reducing or increasing line times this year.
