We are finally going on the "big US vacation" in August this year - myself, DH and three teenage DCs are going to California. Can't wait! We have so far booked flights (into/out of LAX) - itinerary is pretty flexible, but we will try to fit in the usual (LA, Pacific Coast Highway, San Fran, possibly Yosemite, Lassen etc).
I've been before, but just with DH, but as there are now five of us, accommodation is a bit more tricky. If anyone has any suggestions of great/inexpensive/cool places to stay in California I'd love to hear them!
