I personally feel that if they replaced SES with a hit show, like Wicked, it would be extremely popular. Mind you, SES is awesome as well, and I love that USH has a behind the scenes type show, but in it's current form, I'd prefer some extravagant show like Wicked, on the scale of the old Conan show.
I just...can't visualize how busy and tight the park is going to be. During peak times, the park is unbearable unfortunately. And I feel that once Potter comes, it'll be a sardine can year round unit they increase capacity elsewhere.
Universal Plaza will be great, but it'll just help with navigation....hardly anything else unfortunately. But it'll be great nonetheless
