A great concept, walking in enclosed skyways between buildings throughout the downtown area. However there are problems for novice and tourists.The first and largest problem is a lack of signage in the walkways. We had no idea which direction to go much of the time. Second we walked it on Sunday. Everything is closed so there is no one to ask directions from. So I guess that if you walked it frequently you would eventually figure out where to go. But for the occasional user it is at best, difficult.
