Port Adelaide: Slippery floors, but at least spectators can sit without their feet on court. If you're lucky you find a half smoked fag in the car park and can smoke the rest. Probably not a good idea to skull the iced coffee container you find. You can get a good coffee and half stale donut on a Friday night.
Marion: Ceiling looks like it is about the collapse and one time I was there there was a possum in the rafters. Poor spectator seating + you can't walk from one end to the other during a game without walking in front of the coach, or walking on court. The scorebench is tight and seating pretty average.
Hillcrest: Carpark is woeful. Holes and uneven surface is a accident waiting to happening. The only people happy with the lighting standard are the local muggers and molesters. Inside, they obviously used the same architect and floor plan as Hillcrest.
Based on the dodgy carpark, Hillcrest would need to be the voted the worst basketball stadium.
