Take a look at your list of Table Service restaurants and see if you can identify the must dos for you (your group). I happen to love character meals and enjoy picking out TS restaurants when planning a trip..... it sure can be hard to whittle the list down!!! I agree with Nancyg56 that a great first step would be figuring out which characters you would see multiple times with your current plan.
(That said- while I like the approach of one TS meal a day and once in a while throw in a second, there are Dis folks that do multiple TS meals a day and don't fret the lost touring time....even with all the dis expertise available to you, many planning decisions are personal.)
There are plenty of quick/counter service places to eat for your other meals that won't take as much time away from rides and shows (or just being able to wander and soak in the Disney magic

). Many of them have good food and nice settings. For example, if you keep Tusker House (safari Donald is a blast) and drop Rainforest.....you could opt for quicker meals at flametree BBQ or satuli canteen. And, if you decide Chef Mickey is not a must do, you will have more time and energy to enjoy Animal Kingdom at night.
For days that you get down to one TS meal, think about the timing. For example .my family loves breakfast food but not eating at breakfast time. A good TS meal first thing in the morning would be a complete waste with my crew. One of our favorite meals is a late Crystal Palace breakfast - we ride a few rides before sitting down for a meal that serves as our breakfast and lunch. You may decide that your biggest meal of the day is best planned for breakfast.... or lunch ...or mid afternoonn....or dinner........
Once you do settle on your character meals, I suggest checking our

Happy planning!
