I kinda think that, if Blake left Vale, she went to Vacuo. She's trying to distance herself from her loved ones so Adam won't kill them. She may not know anyone in Vacuo, so she could go there. Plus, it could open the way for her to run into Sun, from him finally being able to head over there to see his family, who are no doubt worried about him.

The CCT network is down, the Grimm are growing "stronger, more prevalent" (to quote Qrow), and Vale is absolutely surrounded by Grimm that are headed to Beacon, so travel may be... limited, especially for Vale. Hell, maybe Blake stayed behind for a few months to help get things under control enough to where she could feel comfortable leaving, believing that everyone will be fine.
