Flying to San Francisco with husband and two children (12 and 9yrs). Thinking of 3/4 nights San Francisco, 2/3 nights at Yosemite, then down the Pacific Highway stopping off at Carmel and a few places perhaps for a few nights. Need to be in Santa Barbara for around the 12 - 16. Will probably do a theme park/ studio in LA though don't want to spend much time in LA. Thinking of San Diego and want to end with perhaps 3 days in NY before flying back. First time so welcome any ideas or input.
