Hello. This is a 11 day trip with 2 infants, 2 and 4. We have been to the Oregon coast from Florence to Astoria, Portland and Seattle. Apart from wanting to spend at least 3 nights in S.F , I am not sure where to go to split up the days traveling. We will probably come back up along the coast only to the Oregon sand dunes, time permitting, but I am not sure. Any advise would be great. Thank you. My kids are good travelers and enjoy all things outdoors, but not long walks, we keep it under one hour. Thank you.
