I'm actually quite happy with it.
I always liked FP+ and this gives the added benefit of booking one more at a time after you use your first one.
I think this will encourage people to spread the advanced ones throughout the day which really helps the overall flow since we all know that most of the time people would try to make them for the first 3 hours of park opening so they could start booking more for the rest of the day.
I also like the advanced booking.
I guess you're going to have people that love or hate something no matter what it is.
