Walked by it the other day and it still has some inside work going on in it with the driveway blocked off to traffic. They definately will need that time up to December to finish it offf.
Agree that this is pretty much a business location. It is close to the river and parks, so lots of great walking but not much around there for tourism. You will need to be walking to the Metro a lot and heading out from there. Unless the amenities come out substantially better than the Millennium, then I would recommend staying at the Millennium for tourism.
