We noticed that too the date you mentioned, but also every single day we were at DHS, and once at Epcot. Most times, weather was just fine (ie: no rain). My theory was since it’s spring break and the parks are jammed from open to close, the rides are going full-boar all day and the usual suspects just can’t handle it. It REALLY caused trouble for us and our ASD son. One day we didn’t get to do a single attraction bcz they were going down and return times on other attractions were too long for him.
