Just a suggestion from someone who is a huge foodie and has eaten just about every place on property possible. You have way too many sit down meals and will spend half your trip in restaurants, spend more money than you need to, and have way too much food. This is one of those times, and I learned it when I went the first couple of times, you cant eat everywhere on every trip. Your day 1 alone is way too much. 3 sit downs in one day? Think of it this way. Youll spend 90 minutes at each (walking to and waiting), possibly have a short to 10 minute wait, sometimes more. Youve just spent 5-6 hours of your day in restaurants. And the food snob in me says you are missing a lot of better "quality" restaurants for showy places. Just something to consider.
If I were doing it:
Day 1- Epcot
Breakfast: Garden Grill
Lunch: One of the counter service spots in World Showcase if you are even still hungry after Garden Grille. The Patisseree in France, Fishnchips in England, etc. Or try the Holiday Booths. Good food, variety and drinks. Or go to Tutto Gusto and relax inside with a nice glass of wine and apps. Or the raucous crowds at Rose and Crown Pub.
Dinner: Walk out and go to Flying Fish or Yachtsman
Day 2- Hollywood Studios
Breakfast: Trattoria al Forno
Lunch: Relax and have a drink and apps at HBD Lounge, 50s Lounge, or the new Taphouse with a peice of pizza from Pizza Rizzo.
Dinner: Hollywood Brown Derby
Day 3- Animal Kingdom
Breakfast: Tusker House
Lunch: go relax at Nomad lounge with drinks and apps. The sliders and bread service are phenomenal.
Dinner: Try someplace like Jiko, Boma, Boathouse, Raglan Road, or Homecoming.
Day 4- Magic Kingdom
Breakfast: 'Ohana
Lunch: If you have to relax and sit down for a break, do it at Columbia Harbor House or Pinnochiohaus.
Dinner: Skipper Canteen
Day 5- Magic Kingdom
Breakfast: 1900 Park Fair or Grand Floridian Cafe
Lunch: A counter service OTHER than consmic rays.
Dinner: If you must eat in MK then the royal table is ok for the experience. If you want better food, exit the park as a break and go to either Cali Grill or Narcoosees.
Personally I wont do 3 a day, but, if you must, Id use breakfast for character meals or other "showy" type things and save dinner for more quality meals. Use lunch as relax spots where you can enjoy an adult beverage in a quiet setting unless at MK, then you want to just fine a quiet place to relax.
