Is Cavalier King Charles Spaniel a good family dog?

My family has decided to get a dog since we moved here to Florida in a good sized plot. Anyways that's not my question, I just want to know that if anybody who has experience with this breed knows about it's general temperament I know it differ from individual but still . . . my parent also quiet liked this dog and we also have talked to few breeders about it but I just want to know that do you think it can be a good family dog and if you can share your experience? Also what can I feed it and everything
