Where can i find out whether there will be early entry to Diagon Alley?

I’m confused about early entry. We will be there Jan. 16-18. Is early entry only for the Hogsmead part of Wizarding World?

If so, how best to visit Escape from Gringotts?

Universal do not announce which park has EPA in advance. They confirm it at check in. Off peak was always IOA only but this week it changed to USF only. Unless you can do gringotts during EPA leave it until 90 mins prior to park close. DM should be your priority ride at normal park opening of USF even with exp pass
