OP here. The trip is definitely happening.
I suggested heart set on one or two rides since my experience with kids that age is that you can exhaust yourselves with trying to get stuff done and sometimes having very little agenda beyond the first few hours can make for a nicer day overall.
My first suggestion, in the context of wanting to see all the parks was Epcot first day, then HS, then animal kingdom (and plan on making it a short day) and finishing up with magic kingdom. I checked with a crowd calandar and this wasn't a particular bad way to do things. Plus it does avoid all the EMH parks.
I also told mom to get a
MDE app to get an account and start thinking about fast passes. She wants suggestions on what rides.
Like many people, she's having trouble wrapping her head around having to decide on sit down meals or not so far in advance!
Coincidentally, we are in the parks too with a group of 7. It's tiring enough with all the planning we've done. I really wish she had decided to stay on site (and fort wilderness is so nice and relaxing) and just done two parks. But, considering two days at magic kingdom is a good idea.
For people that stay off site, is a mid day break just not feasible? Would you ever consider a monorail resort lunch or early dinner reservation for a break? Just trying to think outside my usual planning method.
