Really why is everyone having a hard time with this... I'm sorry but this is a no brainer on the win side, I can sit in my living room and pick rides that I know I want to go on, on certain days talk about a win so if I wa.t to go on splash mountain and space mountain, I can already have fp to do this before getting to the park so now cross crossing the park rushing to get fast pass for one and then heading to the other side to wait in line....
Let's look at it this way. On a typical day at Disney, we can easily pick up 5-7 sets of FPs if we get to a park at rope drop. At MK, those FPs will probably look something like this: 2 Space Mountain, 3 Big Thunder Mountain, 1 Splash Mountain and 1 Peter Pan.
The bottom line is under the current system, we decide which attractions we want to pull FPs for.
Under the new system we'd get 4 sets of FP+s per day (rumored), which doesn't sound like THAT much of a downgrade. But when you think about the fact that Space, Splash and BTM will all be in the same FP+ tier and you'll have the choice of making reservations for one, maybe two. The other two FPs will be from a lower tier of attractions, meaning you'd have to pick rides you'd otherwise never dream of reserving (Haunted Mansion, Mickey's Philharmagic, etc.).
That's the part that frustrates me is that Disney is basically limiting your access to the E-ticket rides (much like when there were actual E-tickets to use). I don't mind the idea of having to plan rides 60 days out, my park plans are typically set when I make my ADRs at 180 days out.
The current system allows you to get as much out of the system based on the effort you put in. If you get to the parks early and have a halfway decent plan, you can ride your favorite rides multiple times during the day. If you're willing to trek across the park in 90-degree heat, you can pull that next FP. That effort-based system is being thrown out for something many will claim is more "fair." That debate will surely happen many times over once the system in officially unveiled.
Until then, I'm going to enjoy this last trip we have under the current system in just a few weeks.
And P.S., the interesting option for those questioning how park hopping will fit in is to make all your FP+ reservations for your second park of the day. For example, you get to MK at RD and ride the attractions you want for the first few hours with little to no waits. Then after lunch you hop to DHS where you have reservations to ride TSM, Star Tours and the Great Movie Ride. Yes, it means having to plan your hopping plans way in advance, but at least it's a way to make it work.
