Not planning any Disney trip for the foreseeable future, but if I was, I would likely skip
Genie+ and Paid Lightening Lanes and try something like this. Yes, without Genie+, we would probably end up not doing EVERY attraction. We usually do, but some are done just to achieve that goal, not because we are huge fans. But, I'm simply not going to pay for this service if I can't schedule in advance and for the times that I want.
Trip assumes 8 afternoon/evenings (including arrival day) and 7 mornings. Park Hopper. I'll use the same basic park setup that we used over Thanksgiving Week 2018. Obviously, we'll do more than what's listed. Just trying to show how we might do major attractions without dealing with the Genie+ chaos.
Evening Day 1 - Epcot (get in line for Remy 3 minutes before park close)
Morning Day 2 - MK (Rope drop Space Mountain)
Evening Day 2 - MK (Spend last 45 minutes in Frontierland. Do Big Thunder, then hustle over to Splash.)
Morning Day 3 - Epcot (Rope drop Soarin)
Evening Day 3 - HS (do standby for what we can and get in line for SDD 3 minutes before park close)
Morning Day 4 - MK (rope drop Adventureland)
Evening Day 4 - Epcot (Get in line for Frozen 3 minutes before park close)
Morning Day 5 - AK (Rope drop Everest, do standby for Safari immediately after. Dinoland and a show or two after that)
Evening Day 5 - Resort time and Disney Springs in 2018 plan, changing to HS (Galaxy's Edge. Get in line for ROTR 15 minutes before park closes)
Morning Day 6 - HS (rope drop RNR & TOT)
Evening Day 6 - MK (Fantasyland after families with small children leave. Get in line for SDMT 3 minutes before park closes)
Morning Day 7 - Was designated a sleep-in morning on 2018 trip. Change to HS (Rope drop Runaway Railroad)
Evening Day 7 - AK (Get in line for FOP 3 minutes before park close. Would skip Na'Vi if wait was more than 15 minutes)
Morning Day 8 - Was HS in 2018 with Slinky FP at 12:15. (Change to sleep-in with no FP to fall back on)
Evening Day 8 - Epcot (get in line for Test Track 3 minutes before park close)
An additional approach would be to take advantage of After Hours at MK and Epcot if we stay at a Deluxe Resort. Our 2018 trip was at Beach Club, but prior to that we always stayed at a Moderate.
Anyway. It's doable without Genie+. There still should be time to do most, if not all, of the non-headliners we enjoy.in the time immediately after rope drop and leading up to end of night. A few days would still allow for an afternoon break between park hops. What we probably won't have time for (and any Disney Marketing staff reading this thread take note) would be shopping. No time for Disney Springs and not time left for the shops in the parks either.
