While all, if not most, of Final Fantasy's airships look like a luxury aircraft, the M.S. Prima Vista is the numero uno luxury airship as far as we're concerned. How many other airships do you know have a built in theater? None.
Sure, it isn't the average theater with a large flat screen, comfortable bucket seats with headset speakers and a cup holder, but who is going to complain about flying in the air while watching a live action play?
We'll just forget the little tidbit that the Prima Vista is the home base of the thieving Tantalus Theater Troupe.
