Yes I'm flying to sea tac, coming from Canada so there aren't really a lot of good/cheap options other than major airport. Looks like renting a car and finding parking will be the way to go then! I haven't been able to get a hold of them to figure out parking options sadly
There is also a spa close to the gorge. That might have some different options for you. I am unfamiliar with optional extra vehicle parking. You might be able to fly in to Spokane and get a shuttle but definitely wouldn't try SeaTac or Paine Field.
Which airport? If you're referring to SeaTac, it's a two-and-a-half-hour drive...
