WS in Epcot deserves two visits, one to sample around the world, another for a nice sit down meal. Get a show times guide too, we enjoy shows or music in nearly every country (flags in Italy are meh).
MK has gotten better with it's sit down choices, but you always have the monorail resorts to eat at too. For a relaxing start go to MK then take the monorail to Poly for breakfast at Kona, or a boat launch to WL for Whispering Canyon.
Get to the parks earlier than early with ADRs. Tusker House in AK, Crystal Palace in MK, Garden Grill in Epcot all have good buffet/AYCTE and let you get pics with no one in the park. Garden Grill in above Soarin so if you have the first ADR you often will be able to walk on before the rope drop mob hits.
Search for quick service you can share. Fruit and nutella waffle then mac and pot roast at Friars Nook.
50's Prime Time is a good spot to eat in HS, but it's also easy to take a friendship to the Boardwalk or Epcot to eat. The bakery in France is a nice quick lunch.
Staying at an All Star I recommend not going to your hotel hungry.
As you can see we eat more than ride, but still can get in all the main rides easily. Plan your FPP based on location so you aren't going from one end to the other, and remember you have an hour to use them.
ex. BTMR 10:55-11:55 and SM 12:10-1:10, go on BTMR at 11:50 then straight on SM.
