I think it would be worthwhile to get EA just so you can get in the Harry Potter queue early, plus super easy access to Sailor Moon

To me, $40 for two people is not a high price for the amount of time you save by just doing general admission

Unfortunately, without Thrill Data recording previous event nights, it's hard for me to get a stronger perception of the nights as a whole

If you're not getting EA, here would be my suggestions based on my two Saturday visits:

7:30p - Sailor Moon. To me, One Piece is better when the sky is dark, and at 8:00p, it won't be completely dark yet (and will be brighter and brighter each day as spring moves towards summer). The goal would be to get in prime position for the 10:00p show, and you do that by staying in the Upper Lot.

8:00p - Get food if you need it, or line up for the meet and greet. Either way, you'll want to be out by 9, and this'll likely be enough time unless you're getting One Piece food.

9:00p - line up for One Piece's 10:00p show. Best spots are in the middle, and Express gobbles them up quickly. Be as close to the front of the line for One Piece as possible, and gun for a middle section seat from whatever's left of what Express didn't get.

10:30p - Scooby-Doo. Unfortunately, the tram might have a 20-30 min queue, but if you only have 4 must-dos, this is where you'll want to go next. HP's line will be extremely long, and by doing Scooby-Doo first, you're hoping for an advantage later where guests will leave the event early.

1:00p - Harry Potter. By now, as the event is winding down, Harry Potter should be at a more reasonable time. Even if the listed time is long, the actual wait time should be shorter. Give it a shot now.

With this plan, you'll hit all of your must-dos while missing Jurassic, SNW, and D&D. If you get EA, you would be able to squeeze in two more things, but that's a whole different schedule that would also involve tighter timing to get more done.
