Closing the monorail off peak, what a sneaky Merlin cost cut, as...
It is not a closure in the actual theme park, it saves staff in the stations and drivers, they will make a bomb on express parking, and they can claim they are making healthier customers with all that exercise.
I imagine they will shift the general parking up to the exit gates instead of the monorail station.
They will presumably open the Galactica exit at close to make things a bit easier for the poor punters, though as they don't seem to give a sh!t about their customer base they probably won't bother.
I usually use the express parking, though on 2 visits last year even that was closed except for pre bookers, so we just dumped the car at the top of the coach park.
