Make what? The Parade?
If so, it is possible if you are seated on time, which you may or may not be and you can not control. If you are seated on time and if you order appetizers, entrees and dessert I don't think you will make the parade. If you are seated on time and have only entrees and no appetizer and no dessert you probably can make it.
Can you get an earlier ADR?
Good Luck
It will be close! If you can't get an earlier ADR, I would suggest going 1/2 hour early to check in. You may get lucky and get seated before your original time. I love Prime Time, but the service can be a bit on the slow side. Good luck!
I doubt you will make it. Assuming you are seated in time (and that is a BIG assumption) Your dinner there will more than likely take more than an hour.
I don't see how this will work. Being seated on time is a big maybe and then even if you finish in one hour, you still have to get to a parade spot and will be standing. Not to mentionn rushing through your meal.
I would see about changing to an earlier ADR or a later one after the parade.
I have learned to book ADR's around 3 hours before parades so I have time to get us a decent spot or book them afterwards.
