Yes I realise it's not in the same category. The reason we were looking at the luxury lines was because we wanted a smaller, quieter ship with fewer queues, rather than because we require a particular standard of accommodation and so on. But if we hide in the yacht club area when the noise/crowds get too much, I think it'll be fine.
I don't think I could handle being on a big MSC ship in the Med if I wasn't staying in the yacht club. Italians don't know how to queue politely! That's a horrible generalisation I know, but I've traveled in Italy and honestly when it came to queuing it was every man for himself.
