Prepare to have fun! The crowds can be a bit much, but Disney are experts at the science of moving people; it's amazing.
Get the meal plan.
We went a couple years ago and got the meal plans which was well worth it. Eating at the parks is pricey, and eating at Epcot is just plain expensive. We ate at the Moroccan place and the bill for 5 was $500. Since we had the plan, it didn't cost a thing (beyond the plan, of course). We signed up for 3 meals a day per person and a snack; that was WAY too much food. Every meal at the fancier places is multi course, and plenty of it. If we go again, it'll just be breakfast and dinner.
