Day-of FastPasses

Is there any place to find the chances of getting a day-of FastPass (4th FP+) for each of the attractions? That info could help with creating my touring plan.

This website tracks attractions that are usually booked more than a day in advance. This may help:

Decent way to plan, but there are other factors. Weather is a big one.

Ppl change their plans, and modify (drop) fp’s all the time. If you are refreshing like mad, and crowd levels are in your favor, and it’s not too late in the day, you should be confident to score almost anything except a slinky, fop, rnr or 7d.

Just a suggestion: plan the easy loaders and shows during the fp hunting times, so you can focus on the hunt.
