Luckily, the the FP systems aren't connected between the parks. So if you get a FP in one park, you don't have to wait 'til the stated time to get one in the other park.
They are connected now as is the two previously unconnected GRR and Roger Rabbit...
Plan to get there for park opening or just before each day, get FPs straight away even though you won't need them in the early morning, keep getting new ones as soon as you are allowed (the time when you can get a new one is printed on the FP.
Do PP, Dumbo and Nemo early as they often have long lines
Do TSMM early, get there for the rope drop on opening but wait at the rope by GRR as it is closer.
Remember Cal Scream closes at night for WoC
Do shows in the afternoon when crowds for the rides are at their busiest
Always get FPs, it was normal for me to get up to 7 or 8 sets in a day...
Fireworks are to the right of the castle, try and get a spot in the hub where the trees aren't blocking the castle and to the right of the castle..
After the fireworks go down to the rope in front of the castle and be one of the first into Fantasyland on its reopening after the fireworks... Do PP..
