What time of the day experiences a lull in the lines?

I'm guessing this may have been asked before but now with the new ride I"m wondering what would be the best time to attempt waiting in line? I'm taking my mom to the park in 2 weeks and we really want to try Gatekeeper. Unfortunately she'll want to try some other roller coasters first "to get her ready" so I'm wondering if there is typically a time of day that ride lines lessen. Perhaps during lunch, dinner? Maybe at 4pm before the starlight people arrive? Or, right before closing? Maybe it varies by day but just thought I'd throw this out there for discussion. Thanks!

Im guessing sometime after 7pm.

I noticed last year when my sister and I went, most of the lines were pretty short between 5-7pm. Which is about dinner time for most people.

I don't know but I was there at 6 today and waited maybe 20 minutes for GateKeeper, then around 7:30 it looked like it was almost a walk on but my brother was ready to leave. Loved the ride by the way!

My sister and I usually go on the weekends(Saturday and Sunday)because that's when we can get off work, so my observation is only based on that, and not on the rest of the week. But from what I've seen, on Saturday and Sunday the lines do happen to be shorter between 5-7pm.

Either in the morning during a weekday or after 6pm
