@swordjaw Car or no? Outside or inside?
Frex, Ada's Books; Seattle Chinese Garden; some kind of boating on Lake Union: electric party boat, or rowing a wherry from the Center for Wooden Boats, or kayaking, or paddleboarding; get something to eat at the Pike Place Market and ride the ferry to Winslow and back while you eat; Bernie Utz' Hat Shop; there's almost always an indie film festival somewhere.
