Disney is pretty well marked... as long as you read the signs, and follow the directions they show, you should be fine to find most anything on property.
FQ is very easy to find. It's a Downtown Disney area resort, so look for that. If you're coming from I4, take the exit marked for Downtown Disney (they just renumbered them, I think it's 66)... that will place you on 536... There will be another exit for Downtown Disney just before the bridge construction. Take that. You'll come to a traffic light. That's Buena Vista Drive. Go straight. You'll go through 2 more traffic lights, and FQ will come up on your right. Less than a mile from the first traffic light.
