Flight
For our guests flying these are the 2 airports that will allow you to access the venue and the greater Seattle area! Alaska Airlines has a hub in SEA and typically is the most accommodating with flight options.
Hotel
For our guest traveling to the wedding, here are some considerations. There aren't many good hotels if any at all near the venue. I would recommend that you explore AirBnb/VRBO as their are some pretty fun and amazing options near by! Some fun parts of town are Ballard (Drinks, especially beer, & food), Fremont (Water access, drinks & food), Capitol Hill (Sights, shopping, & nightlife). For those looking to splurge, some amazing hotels downtown are The Fairmont, The W, and The Thompson Hotel.
Rental Car
For our guests traveling here is some information on renting a car versus ride share. (SEA) has an on sight rental car center while (PAE) does not. Seattle also has added taxes and fees that are not typical in other cities. Expect Ubers or Lyfts to be around $20-$40 each way as a norm.
