X2,
Get ready for sticker shock, in King county they have the highest tax's in the state, you have hotel tax, parking tax, food tax added fuel tax, carbine tax,
I believe if they could they would tax the tax ... The further away from King county you get the cheaper it gets, but if your going to drive a car into Seattle get ready to pay thought the noise for parking, last time we were downtown we paid $35.00 for 5 hours an of course tax was included...
Also Washington State has one of the highest gas taxes in the country, all so they can fix the roads which they don't Ugh
Safe travels
