Here's the sentence I want to say : My parents stayed at my sister's for a few days before returning/leaving _________.
With returning, I could say 'home' or 'to their place', but that does not convey that they're not from around here.
With leaving, I could say 'town' or just the name of the current place, but I want a general way of conveying it. What if I don't want to name the place, or it is the country side, not town?
I'm not committed to using returning/leaving. Suggestions that remove these words altogether are welcome too.
Edit: To rephrase, I'm looking for a way for out-of-towners to say that they're going back.
