We ate at Carthay Circle yesterday at around 12:30pm. We were a walk-in and were sat outside on the balcony. Just as we were finishing our lunch, the Pixar Parade serendipitously started. The balcony was directly above the parade route, so it was the perfect spot to watch. The only complaint I had about the lunch was that there was very little shade on the balcony area, so I was siting directly in the (hot) sun the entire time. But we also saw people coming onto the balcony who were eating inside, so it sounds like you can make an afternoon reservation for inside, then simply step onto the balcony when the parade starts. Also, because each of us ordered an appetizer with our entree, we got Carthay Circle WOC seating.
