do what this guys say
they know.
i just been rhere two weeks ago and I highly recommended the coast walk ( if you have enought time )north end, to the aquarium
say 4 hours
the doors open just minutes before gametime but you can spend time on the common area of north station
If you see the big clover in the wall thats a good shortcut to beachside ( under the bridge walk) crossing the hockey field.
I did my own walking ...lol
