If you are serious about getting input, I suggest you provide the following:
How many traveling and ages
General interest
Were you live know and if you ever lived on a coast.
Type of travel (one flight, or a few, driving or renting a camper)
Per diem
How many times do you plan to come back
Great input so far but not meaningful to do wine tour if you are a family with 3 children etc.
San Diego, Orange/LA, Santa Barbara/Ventura, San Ynez valley/San Luis Obispo, San Francisco, Tahoe/Reno all can take 8 days each.
