You know what? Cheap admission with ticket book purchases at kiosks around the park would be the most fun. Old school baby. Plus, very straightforward. You can choose to pay for Rise of the Resistance maintenance or just chill, eat tater tots and watch the world go by. Imagine how much less stressful that would make the vacation. You get up with a terrible head cold and don't know if you even want to go to EPCOT. The rest of the family goes and decides how much they want to do/spend. Even if you don't get the day refunded, your out 30 bucks or something. Not a big deal. Or you go and wander around WS all day while your teenage kids drop 150 each on ticket books. I would hazard that it would reduce stress, reduce lines, increase fun, reduce advance planning. Plus, Disney would make money because people would by new books just to keep every time ticket designs changed. I have two old ticket books somewhere. Look, I'm a loopy old man at work just praying that the kidney stone won't drop into the super pain channel until tomorrow, but right now, I really like the sound of this.
Also, you know how much the crew that doesn't care much much about E tickets or new rides but loves the ambience of the various locales of WDW would spend if on food and souvenirs with this system? It would also alleviate the need of assigning a grandkid to each grandparent for Disney app phone management every time I organized a family reunion. Anyway, back to work.
