I was curious about the Universal Express Pass so I looked it up. On March 1st and 2nd--I chose those dates because I will be at WDW then--the unlimited pass (you can reride attractions at will) is $129.99. I guess that doesn't include tax, but I didn't go further, so I didn't see.
If WDW charged $130 for a front-of-line pass with unlimited rerides (excluding, say, RotR and FoP, which you could use the pass only once for) and limited the number of passes it sold, these would sell out. I would probably buy this for DHS for one day of my trip, but hardly for every day. It costs a heckuva lot more than G+ but the convenience it offers is a heckuva lot more.
Will Disney go to a system like this? Maybe. Maybe G+ is their method of paving the way for something a lot more expensive. Knowing Disney, though, their unlimited express pass will cost 3x what Uni's does and it won't come with a deluxe hotel stay like it does at Uni. Maybe a deluxe club-level stay, assuming a CL room will cost $1,500/night, although I may have underpriced that.
There is no leveling of the playing field if WDW keeps charging for G+ or whatever system it will have. Because as soon as there's an extra cost, the playing field is automatically not level, since there are people--imagine that!--who actually can't afford to add another $15.98/person/day to their trip cost.
There was kind of a level playing field for RotR when it first opened--the mad rush to, in a sense, win the RotR daily lottery. There were innumerable complaints about this, but unless you didn't have a smartphone, which has become a necessity at WDW, the playing field was as level as it could possibly be. Whoever you were, you had the same chance as anyone else of getting or not getting a RotR BG.
Now this has been replaced by the mad rush at 7 am to pay, and if you aren't staying at a WDW resort, the playing field for you is not only not level, you're probably completely out of luck. How this has made anything easier or more appealing for anyone, I do not know.
But I suspect that all the "Disney, you have to raise the price" commentary on the DIS is fueling Disney's plans to raise the price of G+. DISers, please, don't tell Disney they should raise the price on their resorts. Have you looked at rack rate lately? Sheesh. Unbelievable. And few discounts. No bouncebacks. Still no new AP sales. And let's not forget there's all but no housekeeping lately.
I definitely don't think raising the price is going to fix anything, honestly... it will just make people more angry. It might decrease attendance eventually, but there will still be people willing to pay it. I think disney has enough hard core fans/people that even if they had an express pass like option, at $150-$200 it would probably still sell out in seconds and be a mad rush to get it.... and then people would be mad that it sold out in 5 seconds. Charging more isn't a good answer, unless disney really just wants people who have lots of money and not families or middle class America. It's already a stretch for a lot of middle class families to go, without any perks/ up charges.
I hope they can find a few ways to make G+ a little more functional for people/more flexibility to adjust or modify times so it's not fully screwing up daily schedules.
