Flight
There's only one airport near Seattle: Sea-Tac. It's a short 20-minute ride to the downtown hotel district via ride share or cab. You can also take the Light-Rail downtown: it's about twice as much time, but very affordable!
Travel Note
There are plenty of hotels in downtown Seattle, which is where you will be most centrally located to see Seattle as well as attend the wedding. If possible, stay downtown! Another good option is to stay in the U-District, which is close to where we live, and still close to the venue. If you are looking for more adventurous options that may be a little out of the way, we highly recommend Ballard.
