For the way we tour, I fear that 8 hours in the park is going to make us feel rushed. That’s probably weird since we don’t even do every attraction and spend a ton of time just moseying around, but last year we easily spent a full day- 8 am EMH until past 10 pm in Epcot. I don’t even know how we filled all of that time, only had one TS meal and waited 30 min for Soarin’. Everything else was FP or minimal wait. We looked in a couple of shops, watched the concert, visited some F&G booths...
But my point is, an 8 hour park day doesn’t “feel” like it will leave much time for the proverbial rose-smelling, which is my favorite aspect of Epcot.
