I don't do emh at wdw.
If I have access to early hours at
Disneyland I use those. If I'm up early at Uni I uses theirs. But I avoid emh parks at wdw. So that's not even a tiny bit of a perk to me!
We all pay to park. We all pay for dme. We all pay for the monorails and buses. We just don't know how much.
I'd rather pay if I have a car and not pay if I don't.
