Longish post incoming...
I'm glad you posted this, because I felt like there were a number of competing arguments about DAS (in a Genie+ thread no less) and what the abuse actually was. As someone that has used DAS with my niece, I think the system itself, works as it should. Is there an advantage? Yes (though it is not always perfect at what it does), but that's intended and the reason for the system.
I think (?) many can agree the abuse lies in the number of users and whether a valid need or not. That obviously is a slippery slope, but one that should be reviewed. Speaking anecdotally, I can say the number of guests included on a DAS primary's group can be above what is supposed to be the maximum. I've seen it at both Guest Services and at attractions when the allotment (should be 6 including the primary) either slightly or well exceeds that on every trip I've accompanied my niece. This obviously doesn't help LL queue time.
Tying this back into Genie+....
- Remove the 2 Pre-bookings from DAS. When Genie+ adds the ability to pre-book 1 per day this year, I would mirror that with DAS, but to me, that capability and feature should match
- DAS users should not use Genie+ (controversial maybe), but I think it should be an either or and guests should pick one "skip the line" option of the two if eligible for both
- You cannot limit DAS users who have a pass in 45 min for Peter Pan from waiting in a 10 min standby line for Dumbo, that argument just seems odd to me
DAS has been very helpful for my niece and her family, but I will tell you, if they are with me in the parks for a day, they typically do not use DAS and utilize Genie+ instead. An experienced Genie+ user (IMO), is generally going to have more success pulling shorter return times in succession than a DAS user relying on the posted wait times before they can ride something with the LL. There are always exceptions with high demand attractions or hard to obtain Genie+ of course.
I 100% understand the discourse with the lines for Lightning Lane that encompass Genie+, DAS, etc. In Genie+ case, it's a paid service, and now there's even more of an expectation which I think went way over the heads at TWDC. Seeing extended LL lines for Peter Pan, Slinky, BTM etc. shouldn't be a shocker though especially on a crappy throughput ride like PPF. Any high demand ride that goes down for any extended period of time, this happens, and happened when FastPass was around.
Bottom line to me with Genie+ and the Lightning Lane itself is, the parks have done a woeful job of increasing attraction capacity to match attendance, maintenance/downtime issues get exacerbated for both Standby and LL, I'm not privy to LL sales, but I don't get the impression they are capped as much as they should, and of course the DAS issues noted. Working on one of these isn't enough.
