Well, definitely take advantage of FP, and if you're staying at a resort, am EMH might be really handy. You can head into MK, get most (if not all) of the Fantasyland attractions done, then head back to the resort to swim once crowds pick up. You might also pack some toys or coloring books... whatever your son likes to entertain him in line or before parades and shows. I'm sure you'll all have a great time at WDW. Have a wonderful trip!
