Michael - the OP wrote that there are no other aikido clubs in the area - hence the encouragement to keep training. I'm basing my perspective on my own experience - in Japan, as it happens. Some dojo I trained at were hostile to me, either as an outsider to the dojo or as a foreigner. In some cases, I stuck it out and became - eventually - a welcome member. In other cases, I did not - but in every case, I got stronger. With the exception of the rare case where someone tries to injure you (which was, more or less, my welcome in aikido as I write in Dueling with Osensei
), it's more a matter of social unpleasantness.
So let's speculate the OP doesn't move for two years. In that time, they will be, if they really train hard, shodan level, and that's a much nicer skill level to start in a new dojo, that two years absencse and starting all over again.
