MFDS,
Was there yesterday and today of course no problems vacating at W or C in A321.
Yesterday a Saudi 744 landed on 27 and could not vacate at C, another aircraft had to go around as Saudi had to do a 180 so that they can vacate via C. The runway is 150' wide or 49 m, so it should be tight but enough for you to make a 180. It seemed like Saudi had no problem with 180.
I guess it'd be better to advice ATC that you'd be unable to vacate by C and you'd need 180. This way they can maintain more separation saving someone a go around.
