Well, The Universal Escape rebrand never did a good job explaining there's a second park. Folks would be in the studios, see the track for Hulk or DD and ask how do they get there, and then get irked to find out they're in a separate park with separate admission.
We all know the phrase "Build it, and they will come.", but in this case one had to build it -and- properly market it and then the people will come. Universal Escape still goes down as one of the biggest rebrand/marketing blunders out there, and for good reason.
As for EU, it's good to hear things are looking up for it. It's hard to ignore that every weekend the parks have been at capacity, heck when I was down there in September it was easily the busiest I've seen CityWalk since well, ever!
