I get what you are saying.  But giving people a perk that the majority of people that are passholders won't be able to take advantage of seems like not much of a perk.  I mean kids are in school, people are working, etc.  So my complaint of three hours was if I am going to take time off of work to take advantage of this "perk" I would hope for more than just three hours.  Make it worth me taking off work to do.
I also think Disney is sometimes silly for the things they do.  I would think more people will eat at Uni than will eat at Disney as a passholder.  Because you get a dining discount at Uni.  So you would think they could make more money off of passholders if they would just add a 10% discount.  I think they would make more than they would lose from a discount.  I also think this was another silly thing.  Because passholders look at it and go, really?  Three hours...no thank you.  That is what I did.  So they missed out on me going there, paying for parking (if it isn't free), and buying food from them on a Thursday.  They would have made money off of me, but now they won't.  Their lose.
