VALET for $2 a day(tip) .............but I would not leave it in valet for more than 18 hours.
The parking garage on the west side tip-------------WHEN YOU REACH THE FIRST LEVEL, BEGIN TO EXIT AND YOU CAN USUALLY FIND A SPOT JUST BEFORE THE LAST TURN.......if not, a quick backup and your ok.
Unlike what a few have stated here, the GN garage is not that scary, just be on the lookout and be armed.
