If you want a top both experience for both Dinung and WOC, go to Carthay Circle. It's expensive, but completely worth it in my opinion. When they say you don't have to get there until 15 minutes before the show to get a great spot, they mean it there.
That being said, if you just want to see the show, on the 15th they added an 11:15 show, which they were still giving FPs for at 8:30 PM. On the 16th FPs were still available for the 10:15 show until at least 7 PM (possibly
Later, but that was the latest that we passed an area that indicated either way).
