Hi, welcome aboard. I can see you are pretty new around these parts!
You are correct about doing table service with deluxe resorts. When new discounts are announced, you have to act quickly, unless you booked with a travel agent, then they take care of changing to free dining for you.
But really, pick a restaurant, just any restaurant, and you'll likely have a decent meal, and since you want to skip character meals, you'll have better chances according to the opinions of others. You have until mid march to make up your mind for your 180 day reservations. In the mean time pull up some of the unofficial Disney dining or Disney food websites, check out some menus, or some reviews. Pick what looks pretty tasty and then ask some more focused questions. As it is, you will find fans of just about any restaurant on property. And since you didn't mention what type of dining you want to have, or what is a no food for you we can't recommend anything specific. Can you imagine if we said to check out The beirgarten, but when you get there you find out you would share a table with someone else? Yikes! Or what about if you don't want to eat something you could easily have at home? Or you want to avoid signature dining, like you could find at California Grille or The Hollywood Brown Derby?
