On the buffett was scrambled eggs, pancakes, home fries, bacon, sausage, biscuits, gravy and grits. They also had small individual sized cereals, bagels and bread (and a place to toast them), danishes, fruit, chocolat and regular milk and apple, orange and I think grapefruit juice. For My grandmother, DD (who is 5) and I it cost $27 and change. It was quite hefty considering you could go to Ihop or Denny's (and both around the corner) get a bigger meal, exactly what you want for much less.
Now that I know you are renting the car I will tell you all you have to do is make a right out of the parking lot, make a left at the light at the end of the block, get all the way to your right and make a right at the first light you come to and you are on Disney property(you can't miss it-there is a huge sign that says "Welcome to Walt Disney World" ). From there, you are about 10 minutes from the parks and only about 5-with traffic-from Downtown Disney. My suggestion-what I learned is going into the property, always stay to your right. Coming out of the property, stay in the middle lane-the left lane turns into a turning lane after Downtown Disney.
I hope that helps! if I remember anything else, I will post to you. I am still kind of jet lagged(we visited family from Friday the 12th until today when we flew home so I have to think to remember!) but my brain should be more clear tomorrow-LOL
