ok now do non-EE parties of 5…going next next Saturday (Oct 4).
When the park opens for Early Entry, everyone is let in, also people who don't have the perk, who are allowed to queue outside the portals for the land of their choosing. For Harry Potter, the morning I was there they told me they were "pre-loading" Battle at the Ministry, ie allowing anyone willing (onsite or offsite) to enter the line. I don't know if they start operations earlier, but it's possible. So this is an option for rope drop, but I don't like it.
To be among the first to ride BatM you'd need to arrive before 8:30 at the park. Then enter the line and hope it opens early and there is no delay. Let's say on average it opens right at 10. You've arrived early, waited for the park to open, waited an hour online plus the time waited for your turn. You might spend easily 90+ minutes on that and you could do that any time during the day. BatM is not plagued anymore by constant problems. Unless bad weather shuts down 3/4 of the park, the line in the afternoon (at its worst) should probably be under 90 minutes, and in the evening it'll fall off a cliff. Sure, you're waiting before the park opens, so that time is less "valuable", but if waking up so early to just wait means you won't make to park close, than it's certainly not worth it.
If I were in you, I'd just arrive around 9:30, pass security and gates and line up for Isle of Berk at 9:40. Ride Windgliders with minimal wait, then the flat ride nearby, I don't remember the name, then Fyre drill, (if desired, I don't think it's good enough to justify being soaked). Buy a Mac and cheese cone on the way out of the land. Then if the line for Curse is still reasonable, do that and then Monsters. If you skip some attractions in Berk, then it'll be easier to do both attractions in Dark Universe with a short wait early.
At this point you're left with shows (do whenever) and the big problem of Nintendo World. You'll never find DK with a short wait and Mario will over around 1 hour most fo the day. Yoshi is much maligned, I found it better than I expected, it's cute, but not worth more than 20 minutes, IMHO. You may just suck it up or risk it and wait for the evening. I think you should be able to do Mario around 9 and then get in line for DK before close (what I'd do, it's a neat ride, but not worth 2 hours, in my opinion). But in case of bad weather you'll miss an entire land.
I don't care for meet and greets, so you're on your own for those.
I don't know if Stardust racers being closed will change things much, but the Saturday I was there this plan would have worked perfectly.
