You know I agree I think Conquest class is a great size. They just need a little TLC at this point and a little updating most would say (although I personally disagree, I like the decor - but I do admit they need more dining options to bring them up to snuff with the competition). Hopefully Carnival can update them without shoving tons of more staterooms in them and removing public spaces like they did Destiny class.
Sadly, however, that won't do much to help Tampa or JAX - they can't accommodate a Conquest class ship at this time.
