I think alot of ideas were covered by the game run forums

Stadium  the immense size (wont be just a basket ball court sized place)

Out in Sea mission  (use of weapons, plasmid)  several scenarios

Department store/Super market

Real Farms  (I would expect cheaply build tunnels in bedrock - huge network of them)

Zoo/carnival was talked of
