Carnival Excel class and Bigger...should they really build them? Or upgrade the smaller ships?

I honestly feel like that Carnival should update their smaller ships, instead of trying to compete with Royal for largest ships. People are going to cruise. They will make their money. I just feel the sacrifices are too great for the giant ships. Crew to passenger ratios, venue and room sizes, even the energy of the fun crew. I have sailed on the Vista and the Jubilee. My first was the Glory. I can honestly say, had the Vista been my first, I probably would have never sailed again. It was like it was the "test" ship to see what people liked the best. So much crammed together. Smaller venues. Jubilee was still smaller venues. They sacrificed space in the rooms(espcially bathroom). Ship, though new, was very plain. Loved the Glory. It was dated, could have used some tlc. The vibe was epic. Pics are Jubilee room entry and bathroom(balcony room). Lounge on the Glory(karaoke). Best spot on the Vista(Havana Lounge)
