depends on whether you want food or characters more:CP is quite good for a buffet, but it's a total chaotic madhouse, and the restaurant's mantra is "don't be away from your table when the characters come by". That meant that my neurotic DD wouldn't get her own food at the kid's buffet, and I had to do her food running, and then my own, and try to be sure that I didn't miss taking the pictures with the characters. I was exhausted by the time we left, and the acoustics mean sound bounces all over.
LTT doesn't have the variety, but it's much calmer, the food comes to you, and the characters don't seem quite so rushed.
