My vote would be for CM. Fun atmosphere, love taking the monorail into the Contemporary. We enjoy the buffet here. The potatoes are to die for. My kids LOVE the desserts here, especially the make your own ice cream with all the fun toppings.
We like CP better for breakfast. We liked LTT but some people really don't care for the food. I think either you like it or you don't. Make sure it's your cup of tea. CP and CM are more "Disney" to me.
