I'd describe it as greater than the sum of its parts, which is lucky as its parts aren't that impressive. The shops are the same, the facilities are the same, the midway games building still looks like crap. The new facades, while a welcome change are pretty bland, and lack the detail that an immersive themed area would include. It's also fairly generic, it could be any shopping centre built in the past decade.
Its unambitious; the Sourthern end feels like it's missing a stage or big screen. The eastern side feels like it should have a proper row of shops (Bar?). For an all weather venue there is no Monorail drop off, so if it's raining it's a 300meter walk through the rain to get to your all weather function venue.
So it's crap right? Well, no. It's a massive improvement. The real breakthrough is the approach from the South, and the way the paths have been done; it makes it feel like the plaza is the obvious way to go through the park, rather than the inconvenience it has been previous. The best feature is the roadway through the middle of the area. Not only does it guide you Through the area without you even realising it, but unlike Main Street there are no kerbs, it's 100% flat in the plaza making it totally wheelchair friendly. It feels like this is part of a master plan rather than trying to fix what was in truth rather unfortunate placement at the start. It's big it's airy and it's pleasant to be in, and that's a big plus for the park.
