Where would they have parked it between flights, had it gone into
service?

SNIP

On the flight deck - which would have been cleared of all other aircraft in
order for the Herc to operate. If you wanted to conduxt air ops you would have
to revert to WWII style flight deck ops - park her aft in order to launch over
the bow, then drag her forward to clear the landing area, then drag her back
aft....you can now see why the angled deck was a "good thing" (admittedly, its
primary benefit was to allow a bolter a chance to shoot another approach rather
than hit the barrier)
