Radiance is my least favorite ship out of Long Beach (though we obviously haven't been on Firenze). It's not that it's bad, it's just not my fav. I just feel there are less options overall on that ship.
I will say that tendering to Catalina took a long time as it seemed everyone was getting off the ship. The hallways were lined with people.
We sail Firenze in October. We're looking forward to checking out a new and different kind of Carnival ship.
Not sure any of that helps.
