and may I ask, not being nasty that is, how do you apply that principle when you just get off a ride that you were online for say 90 minutes but the wait time said 60. You thought you were going to be on time, now you may not be because you are going to run into parade traffic, and it is jam packed with shoulder to shoulder guests? It isn't like you are leaving your room so that you "can" plan on leaving 30 minutes earlier... you were on another attraction whose time was off...

just giving an example of what can and will happen here... can you give us an example of how those guests can handle that situation when they arrive late for their FP return, or do you just propose that they do nothing but stand around waiting for their FP return time to avoid any unexpected situations

again, not being nasty, but would like to hear how to handle this????? tia for your response....
You can't apply that principle to your scenario, but then ... I wasn't answering that question.
The response I gave (that you quoted) was in direct response to a question about how it can often take much longer than an hour to get across the park when the park is crowded, and so if someone were to head to their FP'ed ride to use their FP, it could take until the end of the window before they actually got there. Hence the answer of "start earlier".
In the example you give -- being stuck longer at a ride than you expected -- obviously, that's something totally different.
But based on your example ... if you get into a line with a stated wait time of 60 min, and being in the line a half-hour longer (90 min) causes you to
totally miss your FP window (including the 15 min grace period), that would mean that you got into a 60 min line for one ride when it was only 15 min before the window opened for your FP'd ride. So even if the 60 min wait time estimate is
bang on, you're still only giving yourself 30 min to get from the ride you exit to the FP line for the ride you hold the FP for. That seems to be cutting it pretty close, particularly if you know that you're going to have to walk across the park any time near parade time.
In that case, if it's only 15 min until the FP window opens on your FP'ed ride, maybe do that one first and the other one after. Take a nice leisurely walk to the FP'd ride, ride the ride, and then hit the other one during the parade, when it's line may even be less than 60 min. Basically, it's just planning differently.
All that said, however, if you were to find yourself in a case where you truly believe you gave yourself enough time and life simply conspired against you to make you late, you would do what you do anywhere you show up late for something, whether it's a ride, a restaurant, an interview or a doctor's appt. You explain what happened and hope that you can still do what you want to do.
