I know it's expensive as **** but as a Freo fan spending a few days to a week in Melbourne soaking up the atmosphere of the first ever grand final would be worth it.
Living overseas now, I always said I'd fly back specifically for a Melbourne Grand Final. People laughed when I told them the possible cost but given free accomodation in Melbourne, it's probably a similar price to the Perth fans.
Speaking of which, have hotels hiked up the prices this week too?
