Just use the parking structure on 8th and Market, or on K and 6th st. Both are only $1 an hour on weekdays or $15 overnight on weekend!
Street parking is tough, there are parking lots but expect to pay for it. I recommend a cab or uber/lyft.
Parking in general is getting worse and more expensive in dwtn. Some parking lots charge 20 to 40 bucks depending the night or special event. If you park a little further, you might find one that charges 10 bucks. Best bet is either a uber or lyft.
We walked. The area was pretty busy. Doubt street side parking would be easy
There are a few a garages in the area for the district as well as street parking.
