If you get early entry make sure you get to the gate 30 mins before your EA time because they start letting you down to the land early
If your not doing the band games then you should have enough time to ride the ride once and see the rest of the land, I’d be in line for mummy right when the park officially opens, then transformers and finish the lower lot with Jurassic (jurassic normally gets lines the latest of the three lower lot rides)
In theory you should be able to ride all three lower lot rides in the first hour of the park opening
You can then head up stairs and either walk on secret life of pets or wait around 40 mins for Simpsons
Save water world, Kung fu panda and any other shoes until you ride everything you want and do the shows in the afternoon when lines are peaked
The Harry Potter lines will be long most the day but have almost no wait at nighttime the last hour or two before the park closes
Mummy, Jurassic, HP the forbidden Journey and Mario kart all have single rider, note that sometimes they randomly close single rider
lastly death eaters should be roaming around hogmeade at night time along with the castle projection show
