Universal Studios I feel is for older kids. There really isn't much for your age group.
If you really have to do Knott's Berry Farm, go there before you go to Disneyland. I had been to Knott's many times and it really wasn't for me, I'm Disney all the way. My grandkids kept wanting to go to Knott's. On our Disney trip when they were 13 and 10, I added a day at Knott's. After 2.5 hours they were asking to go back to Disneyland. They wanted to try Knott's again when they were 19 and 16. Since we were in SoCal for a full week, I bought tickets. Again, they said Disney is the place to be. We were there for about 4 or 5 hours this time. Kids....... Show your AAA membership card and save 30% on Knott’s Berry Farm Regular admission tickets
I'm going to be in the parks later this week. Would you like me to get you some park maps? If you message me your address I'd be happy to mail them to you.
I wish you well with your planning.

Yes, that would be really helpful and I would appreciate that.
