I still think Pop Century is a waste of space because it it SO BIG. If it was like 3,000 rooms or so, that can be good. But 5,000?!? It's in of the most busiest places on the resort property, it just means more traffic around that area and a lot more people too.
As for WWoS, it's fun sometimes, and definitely isn't being used enough. I think that if they let a lot more area public teams play there, the usage would be better, or even more, get some stuff the guests can use, like basketball courts that people can play on, soccer fields kids can use, or even a lap swimming pool. Just something everyone who's a guest can use.
