I know there are not guarantees, and I've seen a couple people ask this question, but I'm very curious about which rides are usually open when folks arrive before official opening time. It would be very helpful to have this information to save valuable time in the morning by preventing wasted walking to a ride that is uaually not open then. Maybe if we pool our knowledge we can create a working list. My May trip will be my 4th Covid trip. From the reports on this thread and what I have seen, it looks like this:
MK: 7 Dwarfs, Big Thunder
EP: Test Track, Frozen
HS: Falcon, Mickey and Minnie's, Slinky
AK: Flight of Passage
What can you add?
ETA
MK: Space Mountain
HS: Rock 'n Rollercoaster, Tower of Terror
