I think I mentioned this in a Rise of the Resistance thread, but I can't explain how put off I'd be if Disney opens this ride with the Boarding Group system.
The intersection of circumstances at which Rise sits with regards to opening really doesn't apply to any other attraction. No matter how convenient the Boarding Group system seems to be for Rise, it's nowhere near necessary for Runaway Railway and we shouldn't be encouraging Disney to make a habit of using this system. The idea of using it here, at Ratatouille, and at Guardians (and, presumably then, TRON), as has already been hinted at on these boards, is tremendous and would completely change the WDW-going experience.
The equity that has already been chipped away at by My Disney Experience would suffer a devastating blow - think of having to get up at 6AM every day of your trip just for the chance to get on WDW's newest rides. How is that an appealing sentiment? This is without any indication yet of how long Boarding Groups will be enacted for Rise, and therefore no idea how long they would choose to enact Boarding Groups for any/every other new attraction.
I recall some poster(s?) saying back at opening that the system wouldn't even last this long, and yet here we are with no sign of when they will simply open the line to guests. At this point I can't imagine it will be soon, since they seem to be happy with the way it's working out over at Rise despite the ride's lack of reliability. Wasn't that at least part of the point? To be able to dump the line when the ride goes down while affecting a minimal amount of guests? If every new ride needs that then there's a greater issue at hand.
The bonus for Disney is that it gets guests out of a 10hr queue and back into the parks where they'll actually be spending money . . . which was also the point of Fastpass, but at least you didn't have to wake up before dawn every day to use it.
All this is said by someone who was able to get on Rise twice this week at DHS by waking up early for the virtual queue and was very, very pleased with the attraction. The system was nice enough and it did work, but if every new ride starts using this I shudder to think of what it will turn WDW into. It's fine as a unique exception to the rule, and Rise is exceptional enough - on many fronts - to warrant it. But let's not do Disney the favor of letting them think this could or should be the way they open every new major attraction. That would be such an ugly turn for the resort.
I'm all for Disney looking at ways to reduce the amount of time guests spend in line, but this ain't it. Let this be a one and done for Rise of the Resistance, and let's hope it's done with sooner rather than later.
