WCT is the place where you can get a good view of the Pixar Play Parade - if the circumstances are in your favor. Disney Dining used to not ask you to choose indoor or outdoor seating for WCT when making a PS over the phone, but apparently, now they are asking people to choose, according to several reliable DIS-ers. We got lucky when we went to WCT in December, at night. It was 40 degrees and we were the only crazy people who wanted to sit outside. We are all from California but the hostess/CM thought we must be from a cold state if we could tolerate sitting outside!! So they put us at the best table, kind of along the perimeter of the patio - overlooking the parade. Now you are not eye level with the parade; you kind of look down on it a little, but it is a good view. The thing is, unless you get seated at one of those specific tables right along the outside perimeter of the patio, you won't see the parade. There are other outdoor tables that offer no view of it whatsoever.
So I am inclined to think it is timing and luck. If you go at a time when lots of folks are dining outside, you may not get a prime table unless you are willing to wait a long time for people to clear out. But it is worth a try!
