Just my 2p....
We prefer to FP stuff we really want in the morning and try to grab more on the fly for the afternoon/eve-just be cautious that it's unlikely you will get experiences which are not at the top of your list. For example we were there in February (technically a low visitors week!) and we wanted to do buzz in MK but I didn't prioritise a FP for it and by 3pm all FP were unavailable for this attraction where they ordinerily should have been. Aladdin carpets on the other hand I could get! (Based on a party of 3 people) sayingvthis- some people do cancel their FP plans which means they are put back in the system. For example on the same day-we managed a 1pm FP for PP which wasn't there earlier.
Parks have a tiered system too which means that you can't for example get a FP for the same day for both sorin' test track and frozen ride in Epcot. You can only pick one of these and two from other attractions... Like figment and nemo. This is with the exception of MK which has no Tiers.
Anna and Elsa m&g does not have a FP so that is a queue only! I have heard however that it is not as crazy as it was in MK to see them... But then in summer who knows?!?
So basically choose 3 attractions which your party wants to do for sure per day and be more flexible for the rest. As there is a big group of you-sometimes if you are trying to get FP for more than 1/2 people, it may say there are none for the partY-but of you look individually-they sometimes come up-e.g one person gets sorin' at 11:50, another at 11:55, another at 12:00 etc... But you all ride together in the same ride window of 12:15...
As you are doing rope drop too this will also help!
You can book FP for the second park if you hop once your initial 3 are done which is great! E.g done 3 in MK and hop to HS where you can get another.
(You missed Star Tours as a FP for this park
I personally don't see the need for a FP for AK Shows as they have big capacity but again when we were there FotLK was full so did turn some stand by away-that plus pandora opening - crowds are likely to be higher for AK for a whole... Again book if needed to see! I don't think you get better seats tho for doing it. The frozen stage show in HS however I think are good seats for FP as you are seated nearer the front
I'm sure most of this is covered in the FP+ sticky thread as meantioned but I thought I wound post as I'm stuck for a whole putting baby DS ti bed (fingers crossed for more than 3 hours tonight!)
Happy planning!
