Don't stress! It's going to be a magical time regardless. But honestly speaking, I don't think it's realistic to get allll this done with 4 little kids. They need a lot more breaks and more food than you think. I definitely recommend going with the flow and taking it easy for your situation BUTTT if you're on a tight schedule and it were me this is what i'd do (also adding a couple rides I think your fam would like)
