MCG has 36 bars, most with view of the field, some also with view over Yarra Park, 14 dining rooms, no queue food and drink outlets, food courts, four parent rooms, kids playroom, sensory room, excellent disability access and seating, escalators and lifts to upper levels, cushioned seats on middle levels, vast majority of seats undercover.
AAMI is similar other than food and drink outlets not as well laid out.
I would imagine any stadium built in the last 20 - 25 years would have most of those facilities but half of the SCG is more than 40 years old. The current capacity is fine but people expect and deserve more these days.
Will never be used as an oval again.
