The WUC has a small parking garage that may be full when you arrive if there are other events at the same time. Attendees are welcome to park for $10 at Coast Hotel at 1301 6th Ave. Take your parking ticket to the WUC front desk to pay, and they will issue you a QR code voucher with instructions. When exiting the Coast Hotel, insert your ticket and use the QR code to exit the hotel parking garage.
There are also other parking garages in the area for reasonable evening rates. You can look up and pay for parking at SpotHero.com. The link is prefilled with the WUC address–add the event date and time for accurate cost.
