I agree with everyone else so far... take your time.. take path's you've never taken before, go to areas you probably skip, see/do attractions you might normally skip, etc...
Watching people is fun... my wife and I do that all the time... It's fun to see the difference in people even between different parks and areas... Like how the people at MK act different from the people at Downtown Disney... etc...
Something else that my wife and I do, is that we will spend a whole days going from resort to resort... See what the different resorts are like, how they are decorated/themed, the different food choices between resorts, etc....
We'll park at Downtown and use transportation all day... It's fun to try to use every form of transportation available in one day (trams, busses, Monorail, ferry boat, friendship boats, etc...)...
One thing about being an AP, you get in the "habit" of not standing in line and waiting on things... unless you really want to ride... because you know you can always come back later
