Vacation Ideas!?

Hello Everyone! My husband and I would like to take our girls on a little vacation! They are 6 and 2. We live in central California (so the middle lol) so any drive would be about 4-6 hours, north or south. I looked into Disneyland, legoland, Knotts berry farm, and seaworld. We took them to Monterey bay aquarium last year and they enjoyed it. Anyways, I know my 6 year old would enjoy any of these but I want my 2 year old to be able to enjoy things as well. She loves Mickey which is why we were looking into Disneyland. Anyways, if anyone has any advice or suggestions, it would be appreciated. Thank you!
