I forsee this as crap show IMHO. At $15 a person, for a family of 4 it's only $90 bucks a day for the Genie+. But here's 7 drawfs mine train *notification* "Skip the line for $25 per person" Family of 4 pays it, another $100 bucks, now you're in another $190. Then I'm having to walk around the park all day, looking at the app and see which attractions have a LL spot available...oh wait here's one in 2 hours. So I now need to kill time for those 2 hours, maybe I get on 1, 2 or 3 attractions in my time, maybe none since the lines are too full. Then you have to imagine the amount of ankles and people getting bumped into since everyone will theoretically pay the $15, everyone will be walking around on their phones, and at the end of the day its going to make the experience worse. Bottom line as many are saying Disney is squeezing for every dime out of you, and it always feels like they are trying to cater to an upper middle class- high class visitor with all of these upcharges.
I like it the way some people describe it online, this is a Disney Parks' version of DLC.
