Don't kno if it's the best place to ask this... but...
If I subscribe, and travel... after my subscription time ends, will I get back to NY, or will I stay where I was?
i believe you will stay where you were when yor sub ended. Travel is limited to subscribers only so you would have to stay where you were at the end, but that is not always a bad thing :).
Yes, you do stay in the city you were in.
That's okay though because the other cities are just as good, if not better, than NY.
You can, of course, just come back to NY before your subscription time lapses.
