Haven't been to Disney in awhile, and we last time we skipped AK, but from what I know, I will say the same.
All four of our family will definitely use Lightning Lane for: Flight of Passage at AK, Star Wars Rise or Resistance at HS.
The rest may vary (e.g. just kids getting Space Mountain at MK)
Guess the others will depend on the wait times on that day. I do really want to try Frozen, Remy at Epcot and Runaway Railway.
As for
Genie+, that's a tough one. At Epcot for example, totally worth it for Soarin and Test Track...but then you can only book each ride once via Genie +, and nothing else is really worth it from what I understand with current wait times. So do we splurge and get it? We will have 2 Epcot days, so maybe we will bite the bullet for one of our days?
MK seems worth it for Genie+ as there are a lot of rides included. But both days or just one day?
At HS, I guess Genie+ is worth it just for Millennium and Slinky Dog dash, and then Toy Story and Star Tours...so most likely purchase it.
Definitely makes it interesting for a different kind of planning.
