What are must-sees in a California vacation?

The ages of the kids are around 13, 14, and 14 and other than that they’re all adults. We plan to go to most of the cities and hit Las Vegas in Nevada. We’ve already decided we’re not going to Disneyland, but we are going to Six Flags Magic Mountain and Universal Studios. Help would be appreciated. We’re not too much into sight seeing except if its really cool or important. Thank You!!

Where is a good place to go to for vacation in California with 2 young children?

We have a 6yr old and a 1 month old and want to take our family on vacation this summer looking for something in California.

I need an itinerary for a vacation in the San Fransisco area. Please help!?

We are planning a romantic getaway and I know nothing about California. We would like to see all the sights in San Fran but also maybe take day trips to Napa Valley and see the redwoods. Any suggestions? Hotel recs? Thanks!!
