Stopped in today to pick up our race packets (Pittsburgh Marathon, Half Marathon and Marathon Relay...etc) and to browse around the running related booths.
Our event was up on the second floor. The space is absolutely gigantic. The expo room itself is quite vast and so is the space outside of the main room. The event was quite crowded, but due to the size of the place, you had plenty of room to get around without shoulder bumping people constantly. They have glass windows all along the one side overlooking the river. In addition, there are some balconies you can go out on to take in the views. I like the views (I know the river is brown) but it is still something I enjoy.
I am amazed at how clean this place is for how many people are there. The bathrooms were also really clean as well.
They have a rather large parking garage as well. Though parking is ample, it can get filled. And since it is downtown, the parking is expensive.
