So, here's another revision on our schedule.
Day 0 (Tue, Aug 14) Travel Day
Day 1 (Wed, Aug 15) Universal
Day 2 (Thur, Aug 16) Checkout/More Universal until mid-afternoon/Food Shop/Check In PO-Riverside
Day 3 (Fri, 17) Magic Kingdom (EE)
Day 4 (Sat, 18) Animal Kingdom (EE)
Day 5 (Sun, 19) Hollywood Studios (EE)
Day 6 (Mon, 20) Animal Kingdom (EE)
Day 7 (Tue, 21) Rest Day (Sleep in, few hours at a water park)
Day 8 (Wed, 22) Epcot
Day 9 (Thur, 23) Epcot (EE)
Day 10 (Fri, 24) Magic Kingdom (EE) / Afternoon flexible
Day 11 (Sat, 25) Rest Day (Sleep in, few hours at a water park)
Day 12 (Sun, 26) Magic Kingdom
Day 13 (Mon, 27) Travel Home
I think Day 9 & 10, after our mid-afternoon break we may decide we want to swap to another park, depending if there are other things we want to do again.
Thanks again for all the advice!
