We’ve been mining these during our stay. Our strategy has been to book rides likely to go down or that are already down and hope they stay down until the LL window opens.
N.b. Passes convert about 5-6 minutes before your window opens (probably consistent with the grace window).
One weird thing o noticed is when we mined pirates the anytime pass was ONLY valid for pirates. The time was open, but the ride had to be pirates.
I’m currently holding a pass from haunted mansion going down:
Excludes: Indy, Minnie Mickey railway, space mountain, rise of the resistance, Matterhorn, Peter Pan.
DCA excludes: guardians, Toy Story, radiator springs racers, Webslingers.
Also note the anytime is valid for some rides that don’t have LL.
I know we had an anytime from toy story yesterday that we used on Webslingers. So they seem to be in the same level group.
