I live in Tacoma too, and if I weren't already going to be in Anaheim, I'd take you guys to the airport! I can't even imagine parking for that long...when we went on our honeymoon we were so against parking that we took Metro (living in Fed Way at the time) to the Amtrak station in Seattle, to get to Vancouver to get on our cruiseship. My anti-paying-for-parking mind is hurting for you.
Though we *might* pay for two days' worth, b/c we leave on the 6th in the evening, and DH has to get back on the 8th. Friends get annoyed if you ask them TOO often for rides.

Then again, I tend to pay the friends with cakes, so everyone is happy.
