Yes, but in the "every single attraction" video, Molly criss-crosses the park many times. She's also a pretty fast walker. She has even specifically said that the only way to get your money's worth from
Genie+ is to criss-cross the parks. And that if you prefer to minimize walking and do attractions in the general vicinity, that Genie+ might not be for you. Or, at the very least, you won't get your worth out of it. She also fiddle-faddles quite a bit. Which she did with FP+ too, but it seems to be taken up a notch with Genie+.
Many of us can't, or don't want to, walk 30 miles a day at the Magic Kingdom going from one end of the park to the other.
As far as a planning....it's a huge change, which I have already mentioned. There is a big difference between knowing the actual times that you will be doing a particular attraction, and you can plan your day around those attractions and those particular lands. You will also know, generally, when you can eat lunch or go back to the resort, or leave for the day.....and being sort of at the mercy of the G+ return times. And, even if you don't mind fiddle-faddling, it's not like you are given options....options that you can choose to coordinate with your day. (And yes, sometimes with FP+ there was only one time option, but a lot of the times, there were multiple to choose from)
Listen...this system is the system we have....so I have every intention to watch the videos, do the work, analyze the times, and maximize it to the best of my ability. But, I still think this is a lesser product.
