Planning a trip with my husband and 16 year old son. I know what I want to see but unsure of order. Flying in from Philadelphia airport in either June or August (which is better?) Would like to spend time in San Franciso, would like to see Carmel, Monterey, drive the Pacific Coast Highway and probably as far south as Morro Bay. Absolutely want to see Sequoia National Park. I'm having trouble figuring out the order of the trip - where to fly into and fly out of to go back home. Looking at 8-9 day trip. Any suggestions?
