When they started working on that stage in Celestial Park near the fountain, in my mind I was sure it would have artificial grass to sit on. I was imagining something like the artificial grass area and bandstand at Downtown Disney at DLR. (People really love that artificial grass and there are always kids running around laughing.) I was surprised when they poured concrete there.
But there are other areas along Celestial Park like this spot alongside Pizza Moon, where an artificial grass area would be a really nice feature.
