This ..
I think you'll see higher demand for those early morning/afternoon Fast Passes, just so the "super tourers" can get that 4th Fast Pass sooner than later (now with ease).
I know on my trips I always planned my Fast Passes so my last one was done by 12:00-1:00 so I could make that 4th at lunch. (The downside to that is that the first fast pass of the day was usually wasted as there wasn't really a long line that early), but that did give me a lot of flexibility in the afternoon when making the 4th (or more).
You will also see standby lines in the afternoon and evenings go up as more people just grab fast passes "just because they can" ..
I know I didn't go out of my way getting a 4th (or more) Fast Pass just because of the inconveniene of leaving my group to stand in line at a Kiosk. But being able to do this in seconds at a phone while waiting for my wife to use the bathroom? Sure .. I'll grab a Fast Pass for whatever is close (time wise) . Aladdin, Dumbo, Small World . I won't even care. Even if the standby line isn't very traditionally long.
