I was going to wait to do my pre-trip report, but I decided that I cannot hold in my excitement any longer. This is our 3rd trip in the past 3 years, and it never, ever gets less exciting to plan.
October 29th:
6am flight from Newark, NJ to MCO. (This was originally a 7:30a flight that got changed to a 8am and then a 9 am. United was fantastic and let us get an earlier flight due to all the changes. Now we will be arriving at MCO by 9:15a)
Check-in at Pop and then off to the MK (Always our first park)
As we will probably be up at 3am for our flight this night we will turn in early to prepare for the next day
October 30th:
3 people, 4 parks day!!!!
Bus to AK for EMH in the morning (breakfast at Pizzafari)
Bus to MK (where we will have our FP+ rides for the day)
Monorail to Epcot (World Showcase only)
Boat to HS (dinner at HS, QS somewhere); Fantasmic at 7:30
October 31st:
Begin day at MK
HS in afternoon (FP+ will be there), dinner at 50's Primetime Cafe and then I am waiting to see if Pop will do anything special for Halloween. I know last year there was a party by the pool. If so, we will return to the resort earlier for that.
November 1st:
Mini golf at Fantasia Gardens in the late morning followed by lunch at Beaches and Cream. We will then go to Epcot for the rest of the day for rides and Illuminations.
November 2nd:
Full day at MK. We will get there for EMH/have lunch at BOG. We will then go back to the resort for some pool and relaxation and then return to MK for Wishes.
November 3rd:
Last day 
AK day since we do not usually need a full day there. Magical Express back to MCO will probably be around 6pm, so we will have plenty of time if we get there early enough.
We went to MNSSHP last year and my DH did not feel like going again. I am just grateful that we are going to WDW again, so I did not push the issue. My daughter will still dress up and I am sure she will not care about trick or treating too much. We are in Disney after all!
I planned some different experiences this year and other than the one insane 4 parks day (that was all DH; he really wanted to put that on the itinerary), I tried to plan a trip with a little more downtime than we have had on our other trips.
FP+ choices are tentatively decided on. I just need to hope that things work on August 30th when I can make them. My daughter really wants to meet Anna and Elsa, but I was not very successful last year getting that particular FP. Fingers crossed for this year!
And no worries about MNSSHP, I hear the one on Halloween is crazy busy. Good luck on the FP+...when we booked ours at 60 days out for our September trip last year I had several options open for Anna & Elsa. 
I would love to do the 4 parks in 1 day, just for fun 
Can't wait for you TR
