I think a more fair scheme would involve "Reservation ONLY" days where every person going thru the gate is guaranteed to be able to board a ride within 5 minutes of entering the queue. This means, of course, they'd have to drastically reduce the allowable guest count to accommodate that standard. They've done it at night -- they know what that number is. They'd also have to drastically increase the admission cost for those days -- but it would probably even out to somewhere slightly north of what the rubes spend on parking, admission, and Premiere Lightning Lanes, plus tips and bribes.
To make it fair for the out-of-towners and lower upper middle-class families, they could designate one day a week as "non-reserved" days, allowing anyone and their brother (with tickets, of course) to enter and wait in lines as long as they'd like/can stand, with ZERO premium access programs in effect. Those tickets could be slightly less expensive (in the range of High Season + Plebian Lightning Lane costs) since the volume would make up for the lower admission cost.
Someone with Roller Coaster Tycoon - Disney Deluxe Edition* up and running should model this and report back on the outcome...
* This is the version that allows you to segment the guest peeps into those who just pay for park admission, park admission plus limited skip-the-line access, and park admission plus unlimited skip the line access. It prioritizes the PA, PA+ and PA++ so the PA++ guests get immediate access, PA+ gets access after the PA++ guests are accommodated, and then PA guests get to ride after all the PA+ and PA++ guests are accommodated, but with PA line waits limited to a maximum of one hour. At the one hour wait point, PA can override a PA+ guest, or as soon as possible after PA++.
