Here's the thing, you can for sure get "value" out of it. It's really not that expensive. BUT, to me, I used to get that same thing for free not that long ago. I could plan the LL/FP out in advance so that our day had a seamless flow including our dining reservations. And I didn't need to be endlessly tied to my phone all day. Those are the things that make me not want to give Disney any money for a something I don't want. Why would I pay for this?
We did two vacations since Genie + was launched and never bought it once and did everything we wanted to do. We had one day of Genie + gifted to us for an incident at the hotel, and we didn't do much more than we did when we rope dropped and had a good plan.
I can see how some people can like it, it's just not for me.
