Slightly different take. We were there last week. We did not book
Genie+ for the full trip. Only for DHS and MK days, and then for my older children on the day they planned to hop from EPCOT to MK. And having it was invaluable to us. But we didn't use it the way I think it's intended (by Disney at least).
If you just take next available Genie+ times and use their tip board, or whatever it's called, it will have you criss crossing the park and it will make you miserable. Instead, we tended to stack our Genie+ return times for the afternoon and used
DAS almost exclusively in the mornings (and waited in a few short lines). For our Genie+ reutrn times, we tried to stack them in specific areas of a park. And then when it was coming near, we started looking for DAS reutrn times in that area. Utilizing DAS (and booking another one as soon as we tapped in for the last one) allowed us to go from one ride, straight to the next, to the next, to the next as we moved between Genie+ return times and DAS return times. Once we were nearing the end of a particular section of a park, we started looking for DAS and Genie+ return times in another area. Doing it this way, my little guy was able to ride all the rides he wanted with relatively little wait time in between.
I will say though, our "strategy" if you can even call it that, would have been useless in EPCOT and Animal Kingdom because there aren't enough rides close enough together. So we didn't buy/use Genie+ in those parks at all. We relied entirely on DAS and it was fine.
