My usual Epcot routine:
1. Send someone to get FP at Soarin' when rope drops.
2. Test Track
3. Mission:Space
4. Soarin' (usually about 10:30am after this point)
5. Living with the Land (optional)
6. Journey into Imagination
7. The Seas
8. Spaceship Earth
9. Ellen's Energy Adventure
10. Walk to World Showcase, choose WS East counter service lunch
11. Lunch (we usually end up at Sommerfest)
12. Malestrom
13. Gran Fiesta Tour
14. World Showcase Money Spending Tour (Eat, Drink, Shop, Eat, Drink More)
14a. Throw in American Adventure / Impressions de France / Reflections of China / O, Canada
14b. Spend like an hour at Mitsukoshi Department Store in Japan (not required, we always just end up doing that somehow)
15. Catch Off Kilter at Canada - it's really a must see show
16. ADR at a fine restaurant of your party's choosing
17. Catch anything you've missed. Innoventions, HISTA, more time at Rose & Crown, etc.
18. IllumniNations - unless you're us, because we think RoE is a poor excuse for IllumniNations past, so you repeat step 17 or go directly to...
19. Off to the hotel for a night cap!
One should mention that if you stay for IllumniNations, there's is simply nothing like a stroll around WS in the late hours of the night, after IllumiNations is over.
