Sure it can. It is just like letting someone go in front of you. As long as the fastpass line wasn't empty, there is still a space available but the time just gets pushed back. This is the same argument as people not using their fastpasses until the end of the day. The space doesn't disappear, it just gets moved back.
If 100 people are in line and number 50 jumps out, that means that number 100 will get to ride a bit earlier and there will be a bit of time leftover at the end. This just moves everyone else's time up by one person. That time can be filled at any time during the day.
This is the biggest thing that people couldn't understand about holding fastpasses until the end of the day.
No,
Ok, this is actually really simple.
Each ride has a maximum capacity per minute/hour/day. We will pretend that number is 100/hr.
You can divide that number up any way you like it, 25 standby, 75 FP, 50/50, or 100 FP 0 SB. The capacity does NOT change.
Now, IF you want to insist that there are standbys as well, I can do this, although its much easier to prove my point using only FPs.
You can not add a missed time slot from one time to a later time, because you can not change capacity. If the ride is running under capacity, then of course there is space, but you aren't adding a slot back into the system, you are just using unbooked capacity later in the day.
If between 8am and 9am only 70 people ride the ride, you can't add those 30 spots later in the day and have 130 people ride between 3-4.
If I book a FP from 1-2, and I don't show up. You can not add that FP into the system at a later time.
Even if someone from standby takes my spot, there are an unlimited number of standby people, they keep coming, and you don't really impact the levels of standby later by allowing people in earlier.
So again, put it in numbers, if we have a 50/50 split of capacity, and I book an FP from 1-2, and don't show up, sure someone from Standby rides instead. But I can't add that FP spot later in the day, I can reassign a standby slot as FP, and from 3-4 I can split it 51/49. But I can not ADD a spot.
Of course the problem with that scenario is that, as I noted, the supply of standby is not really finite for all intent and purpose.
Its not like there are 600 standby riders a day, so as long as you average 50/hour, you will get them all done. If you let 51 ride one hour, there are still 50 waiting for every other hour.
You can not create more capacity.
