The ARC always impresses me as a venue. What I like is the holistic experience it offers. One year, I remember, I was met at the door by a volunteer and basically directed through the building. The artists worked together as a community to ensure I did not miss a single one of the open studios. This year was not the same experience, but still, I was able to get a list of all the open studios and the names of each participant at the door.
Whereas Parker Street is larger and fabulous, it is a maze and it has an "every man for himself" feeling. I wish they provided a list and directions to the washrooms in a better manner for the public at Parker Street.
