Need suggestions on 2-3 week trip to NW without reservations

While your situation is difficult and potentially stressful, making reservations based on your best estimated available dates gives you a plan to deviate from:) You can always change a reservation date but just make sure you ask what the cancellation policy is for each RV park. My 2 most favorite locations to RV are A. the Calif. central coast beaches B. the whole Oregon coast. The Washington coast is not real RV accessible in my experience but I really enjoyed Whidby Island.
