DLR has a paid FP system - MaxPass. It's fantastic, so much better than FP+. I would love if WDW adopted something similar, even if it did have an up charge. You can make FPs all day on your phone, but you don't make them until you're in the parks, so there's no obsessive pre-planning and scheduling out rides 2 months in advance. It really gets you on a lot more rides with a lot less lines.
