First of all

to the party solo adventurer!
Good news and bad news lets talk about the bad, in 2017 Saturday Sept. 24 and Tuesday, Sept. 26, 2017 both sold out
on the day of the party. There are various reasons for this which include discounts for CM's, Military and AP holders and possibly the weather. Your date Tuesday, Sept. 25th is currently a discounted ticket, only time will tell if this will sell out but the possibility is there.
Good news, your plan looks great and easy flowing. Hopefully Disney will release what specialty treats they'll be offering soon, I would follow that trail and hit up the rides by those locations. We'll work on your plan more as soon as we hear from Disney. Please note, the Haunted Mansion desserts they had last year sold out by 6:30 at some locations.
Quick question, is there a reason you'll be arriving at MK at 5pm instead of the recommended 3:30-3:45?
FYI - It's not necessary to color your time frame
