Nothing specific to the Anthem as far as I know, but a decent specific to the wharf. I'd recommend either pre-pay, or even parking in Crystal or Pentagon City, and Lyft/Uber in. Those are maybe 10-15 mins in, and you might spend more than that looking for a spot.
There are public parking garages underground. Blue signs will point the way.
Yes it's nearby underground. But expensive ($17)
Are umbrellas allowed in?
