Neutral. Wait till you play an away final finishing top so all the opposition fans can go.I really wish the AFL had scheduled our final at Marvel, our last home final was an elim against Sydney at Marvel in 2011. The MCG is basically a neutral venue for us given how rarely we play there, and we won't get more than 50k against an interstate side with a small supporter base. I can't see many AFL or MCC members bothering to turn up to it, either.
I'm going either way, of course, but I'd much prefer it was at our actual home ground than a venue we've played at no more than half a dozen times in as many years.
