Of courses it depends what your tastes are and what your budget is. If the weather is fine, you might consider restaurants where you can eat outside, such as Pecos Bill in Mk and in Epcot, try the one at the American Adventure. (sorry, I've forgotten the name.) If you want sit down service, perhaps you could go to the Contemporary Or Poly for a quiet lunch when you are at MK. Sorrry, you didn't say where you were staying, so I can't help there. At MGM you might try the commissary. Yes, it will be busy at lunch. However, it is a large restaurant and many times I've found a quiet corner, usually quiet a way from the service counter. Another thing you may want to try when at MK, is get your tray, and go toa quiet place to eat it. I've found quiet spots such as at Pirates el Perico (when they are closed) and at a quiet spot opposite Swiss Family Robinson beside Dole Whip. There are tables and chairs, and a roof. Not much for walls, but they are out of the way, hidden with shrubs so very few people notice. At AK, Pizzafari is a very large restaurant, so you might fiond a quiet corner there, although you have no control if a noisy family sits beside you. The food courts at the All Stars are busy and noisy especially where the food service is. However, the food court is huge, so if you walk to the back it shouldn't be too big a problem. Flame Tree at AK has an outside area, so there shouldn't be echo there. Hope this helps. Sorry it is so disjointed.
