Great list!! I also recommended when you have small kids/table food babies, to bring those disposable placemats that stick to the table! Great for easy clean up !
Definitely recommend bringing more than one outfit for the day. I had to rush to do laundry as ran out of clean clothes. Also agreed with shoes I thought I would wear my Vessi running shoes but I got massive blood blisters(had to go to urgent care) so great video and packing list.
It's great to mail postcards from the parks! They'll have special stamps from each park! And the ziplock bags tip is the best! It's one the most useful items.
One thing you did not mention was a plastic or stainless water bottle, because bottle water is $5.50 in the parks. Definitely pack 2 complete outfits per day if it's warm. Sweaty or wet (from rain) clothes bad. Definitely a couple of pairs of shoes - wet from rain bad. We have not found fans to help, much, but a cooling towel works great.
