I agree with this. We had reservations at ohana for 5:20 and were able to get there in time but we were on one of the first ferries after close to the Poly and the line behind us was huge. We didn’t get off our last ride until a couple minutes after 4:30 but must have still somehow made it before the majority of people.Crowds were low with the major exception of Jungle Cruise. It seemed to have as long a wait as ever and ran out of LL quickly.
Leaving the park at 4:30 PM took a very long time. If you want to stay for the low waits at the end of the MK days give yourself a lot of time to hop to another park (like ~3 hours).
