there would be much closer cities to look at besides Federal Way. There is a taxi fare estimator on top right under 'top questions'. Suggest you look at Burien, Seatac, tukwila. Easiest is just to take light rail into downtown Seattle. Many companies will allow you drop the car at seatac for no more money. I know Enterprise will charge.
Thank you Davidgmg. I am headed south, so that is why I picked Federal Way. I am also investigating shuttles to a car agency, but I suspect this may be difficult. I will check out the cab fare calculator.
a lot will depend on when your arriving since many local rentals close at 5 or 6 and may not be open weekends. I'll take a look as well and post back.
I went to \\
and it lets you filter out non airport rentas so you get a good overview. You can also filter out within miles. When I did it some locations came up that weren't super convenient like Bellevue but at least it gets you started.Edited: 7 years ago
