See, there's the big difference between park reservations and FP.I absolutely love the change to Early Entry over Extra Magic Hours. Every park for 30 minutes every day is much more valuable to my family than one park for one hour each day.
I like the elimination of the Dining Plan.
I am neutral on Genie+, TiW, and Annual Passes.
I dislike Park Pass, but I don't feel strongly about it. FP+ already meant that you were pre-selecting which parks you would visit which days.
I hate ILL and the elimination of Magical Express.
With FP you weren't tied to the park just because you had a FP. You could wake up and decide to go anyway. You may be able to change your park reservation but in many cases you can't, the reservations are gone
You could buy a ticket to a park without any FP. Maybe you don't do rides, you just want to dine and go to a show. Or people watch. If there are no reservations, you can't buy a ticket at all.
Reservations have way more limitations than FP did
