Some tips for the long drive -
- foam travel trays are AWESOME!! They let the kids use crayons, matchbox cars, eat snacks, etc. with minimal risk of dropping stuff. I'll find a link to them.
- your older child might be more comfy with a crate or something as a footrest to avoid the leg tingles from dangling feet for that long.
- make surprise goody bags ahead of time (brown paper bags with Disney stickers that hold dollar store toys) and space them out for the duration of the ride.
- keep a portable potty in the back if you've got kids that need to go NOW.
- what kind of carseats are they in? Ours are all still in 5 point harnesses (oldest two in Britax Regents up to 80lbs) so they can lean their head on the side of their seat to snooze. If you've got any in boosters, find a way for them to nap comfortably.
- don't laugh at this (and I know there are folks that will take this the wrong way!) but the boys like small frequent snacks during the trip and the best way we've found to keep things like grapes and fruit from rolling around and ending up on the floor is to use cheap, small plastic tip-proof dog bowls. They each get a bowl that sits in the corner of their travel tray and we keep it filled with grapes, crackers, raisins, whatever their snack of choice is. They do make tip-proof bowls for kids but thanks to the marketing geniuses, they're quite a bit more expensive. Go figure.
It can be done and it can be fun. Honest. You just need a sense of humor. And a lot of patience.

What I love about this one is you can leave the strap that goes behind the carseat in place and just unclip it when not in use. Or you can just unclip one side and lean it against the seat.
