1. Well, obviously there's the must-do sit downs (Teppan Edo, Be Our Guest, Kona for breakfast) but also the good QS locations, Seasons being my favorite. And everyone must enjoy a churro
2. Everything! At least get them on TofT, RnRC, TSM, Star Tours, the MK Mountains, 7DMT, PofTC, Jungle Cruise, IASW, EE, Safari. Dinosaur.
3. Fantasmic. And Wishes and Reflections of Earth, but mostly Fantasmic
4. I tried the Beverly soda thing on my friend. She actually liked it. That backfired. Not warning my friend about some of the scents throughout and the expression on her face while I was holding my nose was pretty hilarious.
5. I took my friend on basically everything, but if you're pressed for time, stick with the good stuff and avoid the "filler" attractions (SGE, Imagination, Ellen, etc.)
6. The monorail resorts at the very least. AKL too if you have time.
