I'm going to assume since you are going to be in the area and are getting an AP you plan on going often. Most of the uber planners only get to go once or twice in a lifetime so they are trying to maximize their trip, that shouldn't be necessary if you will be going often. Things to be aware of - Fast Pass +, you can book your rides in advance now, you can book a ride, ride it book another one in a different park or the same park after you have tapped the first one on the tap thingy at the ride. You can also book 3 in one park and after you have used those 3, book more. There is a thread here on the boards with all things fast pass, you might want to read it. Keep in mind, you can still go to the parks and get in a line and ride a ride, we do it all the time. The lines can and do get long now so if you have your heart set on a specific ride, make a FP. Again, as an AP holder and most likely a frequent visitor,if you miss a ride, no big deal, you can hit it another time. There are some table service restaurants that some feel are must dos, Be Our Guest in MK is one of them (personally I don't like the place so it certainly takes the whole must have ADR thing off the table for us). If there is a TS restaurant you just have to have, it's advisable to make an ADR as soon as you know you will want it. We have never, ever, never, ever, never, ever had any problem booking a TS for the same night by just getting on
MDE during the day and finding whatever is available. The advantage of being an AP holder is you can hop from park to park so the sky is the limit with the exception of those popular ones.
I would suggest the first time you go back to the parks just go, not a popular opinion. You will be able to go back again and this will give you a feel for the lines, crowds, etc. Maybe the night before or even morning of jump on MDE and see if there are any FP+s available for what you might want to ride. It doesn't hurt to go ahead and book them and if you don't use them, you can always either change or delete them.
