Hotel
This hotel is only 12 minutes away from my grandparents house
Flight
If you fly into SeaTac airport you will need to rent a car, it is about an hour and a half drive north to Bellingham. If you want to avoid renting a car, you can fly into Bellingham but will have a short layover at SeaTac airport.
Travel Note
It sounds like it's very difficult and expensive to get a rental car right now. I found a shuttle that will take you from SeaTac airport to Bellingham airport or the Sheraton Four Points for about $45
Rental Car
This is a great alternative to rental car companies, people rent out their personal cars like an airbnb
Travel Note
Parking at the property will be limited so please try to Uber or carpool. There will be two driveways you can pull into off of N Shore rd, look for the balloons!
