Local knowledge: Hagrid's is not on Express. Ride it in the first thirty minutes or in the last hour before close — those are the only two cheap windows.
How this is worked out
Each day starts from how that weekday normally runs at Islands of Adventure, learned from our own recorded wait snapshots as they accumulate, and is raised for public holidays and school-holiday periods. It is a forecast of relative busyness, not a promise: a 3 means a day that usually runs quiet for this park, not a guarantee of short lines. The further out a date sits, the more it leans on the weekday pattern alone.
