I'm taking family for one day with a stay at Helios, is hitting Ministry right at 9, being one of the first from Helios, a good strategy. I see it open sometimes for EPA and not others. Not sure if it is random or not since it is not officially listed as open and it just depends on ops that morning?
My other plan is to knock out Curse with no wait, hit Stardust a couple times, hoping it's running first thing, then line up for Hiccups.
Mario is to unreliable for me to try first thing and I'm not super excited about it anyway, plus it's actually a disadvantage starting at Helios I heard.
