First, we fly in from the west coast, so 7 am is 4 am for our first couple of days. OTH we loved the evening EMH which have been severely curtailed. Second, we like to eat at the signature restaurants & I suspect Disney likes for us to eat there as well since that adds to their coffers, w/ pre scheduling our ADRs & our FPs we knew that the framework of our days were set, we’d be riding some favorite rides & not fretting about making our ADR times because we had some control over our schedule.
W/ G+ you literally have no clue when you wake up at 7 am day of where & when your first ride will be & you have no clue where or when your next ride will be or the one after, I hate it, it’s like you’re paying for a grab bag w/ no idea whether you’ll actually get a decent number of rides for what you paid or a couple tier 2/3 rides spread hours apart.
It works at DL/CA because there are so many rides & it’s very easy to hop between the parks, my G+ experiences at WDW have been less successful, it’s a lot of money for, IME, very little return.
My sense is that because it’s a paid system they move the LL much faster than they did the free FP lines & that’s resulted in ridiculously long standby lines.
I know nothing about technology (other than IME Disney’s is really bad

.) But, the
DAS system allows users to schedule 2 rides per day up to 30 days in advance, so I assume that they have some pre scheduling technology built into their current G+/ LL system.
