Personally, if I was moving somewhere without an aikido dojo or at least an interested human to informally practice with, I would
a) find a way to move somewhere else
b) find something else to do during the time I'm living there, until I was able to move somewhere more sensible. Maybe try another martial art, maybe start rock climbing 4-5 days a week instead of once a week, maybe something else entirely that also interests me and is physically active. Meanwhile try to figure out how to get back to civilization.
To me, trying to train primarily by myself would not be something that would even interest me enough to bother. But to each his own.
