With SeaTac it’s be a long wait yo get theshutyle bus to get to the car crnter

when I’ve returned the car it really hasn’t been that bad

forgasstations prior to return...there are a few on international north of176th and there is one just off 405. You can enter return off of international.
after return just upstairs and wait for a bus. Busses aren’t a long wait.

a far bigger factor is when isyour flight. There are busy times where tea is a pain and other times it’s not so long.
