This was our second big ship cruise, our first having been with Carnival Paradise, which was a smoke free ship at the time. We were eager to try something different, though we did enjoy our previous cruise.
Prior to leaving, I read a number of reviews, and searched for the areas that seemed to be common problems, which I determined were:
Bad coffee; Lack of space in the room, specifically the shower; Crowded public spaces; Long wait times for dinner or shows.
