Interesting to consider, thank you. We have cruised on Royal Carribean, and Norwegian, and are very surprised to prefer Carnival. I say "surprised" because at the low price point we weren't expecting that much when we took a short Mexican Riveria cruise with friends a few years ago. We lived in San Diego at the time - the cruise port was only an hour away, so why not. Turned out to have a very charismatic cruise director (MarQ), good food, and a house band so fun and talented that my husband hung out with them and they are still FaceBook friends all these years later and stay in touch. Our balcony room was spacious and quiet, service was great. I will say that my research indicates that the Luminosa is inferior to the Splendor in some ways so we will definitely book Splendor.
