They're both really good, in our experience. Really depends on how big a meal you want at lunchtime. We tend to have our biggest meal at dinner, finding that a large meal at lunch doesn't sit well when touring in the Fla. heat.
So: if you want a large meal, or your family prefers to select from a large variety of foods, or you want a character meal experience, then choose CP.
If you want a smaller (and quieter) a la carte meal, then choose LTT.
ETA: we almost always do CS at lunch, keeping our TS credits for the (usually) more expensive dinners.
