From our experience, this is a downgrade from FP+. Take the $15 per person out of the equation, it still is an inferior product. First problem is they have taken the “top” rides out of the normal FP pool. Second, they do these weird drops throughout the day. So you have to figure out the drop times of each ride. Third, just because you see and select something doesn’t mean you will get it. Super frustrating to select a LL at 9am and see that slide all the way to 9 pm by the time you get done booking it. Fourth, changing a LL is a risky proposition. Fifth, good luck getting a decent touring plan. We walked more zig zagging the park using g+ the we did with legacy FP. And now, somehow, the standby lines seem longer.
One thing better is the actual wait times of the LL ARE far less than what it was with FP+.
