Genie+ was worth it for our family, first time Disney Land visitors with no immediate plans to return. So we were in the camp of people who wanted to do everything at least once.
We have been to Disney World several times back in the early 2010s, and had worked out a pretty good plan to work our way through the Magic Kingdom based on a popular website plans. We had gotten pretty good at minimizing wait times with Fast Pass. And I felt pretty confident based on the rope drop plans on this forum.
I found the phone app pretty user friendly. As the tour guide, I was on my phone anyway using different apps to check standby wait times so the rest of the gang could just enjoy the day. It wasn't that much time once I got the hang of it. It's possible I spent as much time on Pokemon Go at the Parks as checking on Genie+
It was frustrating to only be able to do one LL per day, but we had three DLR days so we did get multiple rides on everything, it was just once per day for some things. Space Mountain was the favorite, so we LL'ed it every day and rope dropped it once for 4 rides total.
One way Genie+ really helped was with the crowds for not-headliner rides. DLR crowds were 7 or 8 out of 10 all three days we were there, so really got crowded around 11. One day we had thirty minutes to kill in Fantasyland before we had to head to Galaxy's Edge for Moof Juice/lunch and ILL for RotR. Standby wait for Small World said 30 minutes so we got in the standby line. 35 minutes later we were still 10 minutes away from even riding and we kept watching all the LL people go in front of us. We had to bail out of the line. After lunch and Rise we got a LL for Small World and were on the ride in 5 minutes. Ditto for Autopia, which the youngest loved. We waited 5 minutes around 9 am for it, but wait was up to 30 minutes in the afternoon so we did LL and were on in 10.
One thing that helped dramatically was single rider lines, especially for RSR. If I did it over we wouldn't have paid for ILLs for RSR, not least because I didn't realize that the right and left lanes had different experiences, so splitting up meant we could even race each other. Single Rider for MF was a huge help as well, although in single rider you typically have to suck it up and be the engineer. Matterhorn, Splash Mountain, and Incredicoaster single rider lines were key for us as well.
ILL for Rise was definitely worth it for us. Fantastic ride, can't imagine waiting for standby and having it go down. That would suck. Webslingers definitely not worth the ILL for me, although kids enjoyed it because they weren't paying
. WS seemed short and the webs hard to handle. Honestly I prefer TSMM for that kind of interactive experience.
From a budget standpoint it was NOT cheap to do Genie+ every day, but we made the decision to go with a less expensive hotel to free up the $$ for Genie+/ILL and it was definitely worth it for us. We stayed at Hyatt House which was great overall instead of Disneyland Resort.
