Anyone who thinks this will keep Disney from raising prices, or will help extend ticket offerings is just kidding themselves. I just don't see any way this isn't going to be a giant cluster, at least at first, and that's just a terrible way to treat your customers. Disney is basically saying: We assume you're all liars and cheats, until you prove otherwise.
Look, I'm not condoning fraud or even simple mis-use. I also don't condone shoplifting at the local pharmacy ... But that doesn't mean I'm OK with lining up to be frisked before I can exit. Conversely, I will walk through those ubiquitous electronic merchandise sensors, or submit to being videotaped throughout my shopping experience, because, those are unobtrusive and non-hindering ways for the store to protect its interests (though shoplifting, as a whole, hasn't significantly decreased, even with such things in wide usage).
The point is cameras and electronic fencing aren't a hassle for honest customers. Unlike being herded into separate, and limited, lines at one of the busiest places in the world simply for the "crime" of giving them MORE money.
Plus, the rules need to be the same for ALL guests, not just penalizing certain ticket holders AND whatever solution they come up needs to be seamless and relatively unobtrusive (like those sensor gates at store exits). Crooks will always find the loophole and most of these so-called "security measures," end up penalizing no one other than legit users.
Frankly, as soon as you start looking at your customers as the enemy, you gotta think your overall company strategy is a bit skewed.
EDITED TO ADD: This was my experience during our October 5-12 trip with six-day hoppers ... We were asked to put our names on the tickets when we first exchanged our vouchers for them at turnstiles (and given a pen to do so), and then no one ever asked for our names or IDs or anything ever again. I'd say people only checked for hand stamps at reentry, maybe, 75% of the time. (And, if they weren't there, the assumption was you'd washed your hands or gone swimming.) We also witnessed, multiple times, people enter extra magic hours without hotel room keys (we were only asked to show ours one day out of five, though I did usually had them in my hand, so its possible someone "saw" them without asking) and one grown man who entered using his pre-teen DAUGHTER'S annual pass. How do we know? He came back in front of us to correct his mistake ("Oh, you scanned the wrong ticket, she's not with me.") and the person at the turnstiles had to call a supervisor while we all waited. What I'm saying is, from what we saw, Disney is not employing a crack staff of overly observant people. Maybe deal with some of THOSE things, before you worry about herding paid ticket holders into limited lines.
Oh and, why, WHY, don't they have a "no bags" line at the
Disneyland bag check areas (this drove my husband NUTS), like they do at DisneyWorld? So annoying to carry no bags, but have to wait just as long, only to be waved through when you get to the front. It helps no one and clogs up the lines unnecessarily both for those with, and without, bags.
Of course, she was not let in the parks.
Just being the DA for a minute.
