Ooh, good memories lol. Ive ridden to disneyland with my parents four times, preschool, kindergarten, fourth grade, then seventh grade. We always leave at around 2 in the morning, and drive alll day untill about threeish when we reach stockton california. We stay in a hotel called the Radison for the night, to rest and get out of the car. Then the next day we drive from about eight in the morning untill we reach anaheim. We usually reach there around threeish also if I remember correctly. Then we stay at disneyland for a few nights and then usually travel down to LA for a night, and then the next day drive to Redding CA (stay at the red lion lol) and then leave the next morning and drive home. We live in Lakewood, WA. Those cities seem to work great for us, stocton, anaheim, la, redding. It spaces it out manageably. But now that I'm older we finally got tired of all the driving and started flying lol.
ANYWAYS, ways to make the trip easy/fun
Buy travel games for the kids (great ones at
AAA. You don't have to be a member to buy the games, it is just cheaper)
Possibly allow your children to pick some sort of attraction they would like to visit that is not to far out of the way to make the day of travel fun. For example, one time instead of stocton we drove to san jose and visited the winchester mystery house
Coloring books, magazines, wordsearches, books! Lol. Make it a competition? Whoever can find the most words in a wordsearch, read the most book, etc. gets a small prize?
If any of your children get car sick, buy pressure point wristbands. They are around 20$ and work amazingly!
My family always made up a snack box lol. We would go to costco and pick up all kinds of good, no melt, snacks to eat in the car. Goldfish and trailmix are great because if spilt they won't leave greas stains!
I hope I helped! Oh, and don't forget upholstery cleaner, two of the four trips I threw up in the car, and I don't even get carsick!

lol. And it is absolutely miserable sitting in a car that smells like throw up, so don't forget something to clean up with! Lol
