Costa really needs to solve the unruly children problem on their ships. This is our 4th costa cruise and it is getting worse - children jumping into the adult pool and whirlpools. " Adults Only" signs need to be posted in different languages and Costa should enforce the rules as the Europeans let their children run wild with no manners . Adult couples at our evening dinner table complained that it felt like a noisy, family kitchen and surrounded by children. Suggestion: Costa should seat families with children on one side of the dining room and couples on the opposite side to ensure a relaxing atmosphere for those who want an adult dining experience. Buffet restaurant needs better organizational flow as long line ups and different food stations require another line up resulting in eating your food cold when you can finally find a table to eat at. Food at buffet was good in variety and taste (remember that this is European cuisine, not American). Evening dining room food was either very good or not so good, depending on the particular dish. Need more menu choices and without giving up quality. For the most part, good service. Recommend the all inclusive drink package. Lovely ship. Evening entertainment had good dancing and listening music with singers. Evening shows did not impress me but were okay for many of the guests as far as I could tell. I was apprehensive in taking this Costa cruise as I noticed the food quality on my last 2 cruises was going downhill, so, I was pleasantly surprised and hope that Costa finally realizes that many customers choose Costa for the experience of good quality Italian cuisine and takes steps to make this a priority on all of their ships at all times.
