We used this to plan which day of the week for which park. We went spring break '18. We had a great trip.
Did MK x 2, AK, EP, HS, bought a 5 day pass for everyone through one of the places touringplans suggested. Expensive but days 3,4,5 got progressively cheaper.
We used backpacks to carry in fresh fruit, crackers, cheese to supplement the expensive food you can get at the park. The Publix grocery chain is your friend there: great fruit, food, and great t-shirts/towels/SWAG to get there instead of at the park.

We got up way early every day to be parking well before each park opened. Traffic can suck so going early still doesn't guarantee you get in too early. However, this way you can have a decent chance to go to the best primo ride at each park that you didn't get a fast pass reserved with only an hour or so wait or less(or more at the AK rides). We used this method at every park.
We took them on easy roller coasters first, they tolerated them well and we ended up doing all of them.
Using the disney ap and disney wifi was very helpful when it was working which was most of the time.
it is easy to put your cheap ass pancho that folds up like a tiny paperback book in your backpacks. you will need it cause it rains due to orlando humidity.

Go to the East Coast to see NASA one day.
My 10 YO boy at the time and still, was a lego freak. The 8 YO girl at the time, thought lego was ok. They both had fun at Lego-land one day. I was fortunate to be not feeling well enough to go out that day. (haha)
You can buy from the orlando chamber of commerce or some other site online pre-tickets to nasa and lego-land to save bucks if interested.
The kids had a great time. It was a fun trip for all.
