One of the most common questions raised is the challenge of getting a
Genie+ Lightning Lane reservation for SDD because it “sells out” faster than any other attraction at WDW. That is complicated by the fact that ILL$ for ROTR also sells out faster than any of the other ILL$ attractions, so it can be a challenge getting a LL for both, especially if trying to get times in the morning.
Just looking at SDD, there is a general impression that those LL reservations disappear in the first minute. And, it is true that, starting at the stroke of 7:00:00, the return times for SDD go very quickly from 9 AM (for a 9 AM opening) and then to and through the afternoon and evening before being listed as “Not Currently Offered” (NCO), usually within a minute or so.
But, as a practical matter, more return times for SDD start popping up within a few minutes and, usually around 7:08-7:10, times start appearing with more frequency, and remain available for at least a few minutes. Some of those available times can be as early as the 9:00 hour, but there are quite a few more of them that appear with return times closer to noon, and they gradually move later into the afternoon and evening over the next couple of minutes.
I have seen this pattern both when I have played with the app from home and when I have been onsite and was actually trying to book an early time for SDD. One time, after my app froze right at 7 and I missed out on the early times, I was able to land a 9:10 return time at about 7:10 while on the bus headed to DHS.
So, if getting a LL time for SDD is a high priority for you, I suggest trying right at 7:00:00 to get a time. But, if you can’t get an acceptable time in that first minute, I recommend that you keep refreshing every minute or so until the next batch of times comes up. There may be isolated times that pop up from time to time in those first few minutes, but those might disappear before you have a chance to grab them. But, as long as the current pattern holds, some time a minute or two before or after 7:10, more times should start appearing, and you should be able to get something, even if it isn’t your first choice of time. If you’re looking for something in the afternoon your chances of getting a good time are pretty good.
