Sounds like a fun day, with a manageable plan!
I did this same order of parks (plus MK at the end) for our 4P1D challenge in July. Here’s my planning thread and trip report in case it’s useful. We rope dropped FoP, NRJ and KS (then rode KRR after breakfast) at AK; then headed to DHS to ride SDD, TSMM and MMRR (we also watched the new Little Mermaid show there); then headed to Epcot to ride Remy, FEA, Soarin and GotG in Epcot (plus the Moana walk through). We left Epcot (to head to MK) around 6pm. That included two QS sit-down stops (breakfast at Yak &Yeti Local Foods Cafe + afternoon snack-turned-dinner at Connections), and a long midday TS lunch at Sci-Fi.
We were exhausted the next day but had an absolute blast!
Have a great time!
