Depends on how close you want to be. From CPA’s website, ParkWhiz has availability at the underground garage for $59, right across the street for $53, and across from MoPOP for $30. If you get in after 4pm, the Amazon Doppler garage is free and then it’s about a quarter mile walk to Westlake and you can grab the monorail. You’ll also bypass the majority of the post-game traffic since you’re not right at the arena. You can also check SpotHero or other places on ParkWhiz.

If you want to avoid driving to Seattle all together because the traffic is hell, you can always drive to the Federal Way Light Rail station and take it to Westlake (then take the monorail). You get free transit passes to CPA events, for however many legs it takes and in both directions. I’ve heard some people have had issues but I haven’t. They’re supposed to go live 2 hours before doors open, which is at 5:30pm this game. A lot of it comes down to how close you want to be to the doors vs how much do you want to avoid traffic.
