I live in Bellevue, WA and I think you should drive up to Vancouver. It's a nice drive especially during the summer! If you're gong to Portland I highly highly recommend eating at pok pork and getting ice cream at salt and straw! They're right across the street from each other. Portland also has some cute food trucks.
Seattle you need to see pike place and the space needle of course. If you like sushi I'd try eating at japonessa. if you want to try our clam chowder, there's a place called pike place chowder. If you like fresh shrimp I think you should drive up to anacortes and eat at the shrimp shack. Super yummy!!! Anacortes is really beautiful to walk around too.
Shopping is alright in Seattle but I'm sure it's a lot better in Florida haha. If you're shopping for high end bags I recommend gong yo the
Nordstrom in downtown Seattle or the bravern in Bellevue.
