I happened to be up around 7am EST today. I first checked SDD and RotR at 7:04am. SDD showed no G+ availability, and RotR showed no ILL availability. I refreshed for the next 5-10 mins, and both showed no availability most of the time. I think SDD showed one or two different times, and same with RotR.
I haven't tried at 7am on the dot yet, but it seems like the majority of availability for these 2 rides is gone in a flash, much more like the virtual queue lottery than something the customer is actually paying for. Yesterday was supposed to be a crowd level 7 and turned out to be a 3. Today is supposed to be a 6 and will likely end up a 2-3.
As mentioned in previous posts, I believe what we're seeing is a combination of more people becoming aware that G+/ILL exists, and that word is spreading online in the WDW-sphere that you have to get these 2 rides at exactly 7am.
We haven't bothered with HS since before Toy Story Land and GE, so my plan was to spend 2 mornings in HS to be able to ride SDD, RotR and MFSR - ideally each twice with little or no wait (utilizing G+/ILL). I hoped paying for these "features" would allow me not to stress out the morning of...I guess it's the total opposite. I have to hope to get lucky with the return time lottery at 7am or stare at my phone constantly to refresh and luck into a morning timeslot due to another party canceling, or stay all day and use early entry rope drop and jumping in line at park closing.
