Hi amisoll, welcome to Cruise-Chat. Not sure which cabin you are looking at, but I doubt you'll have much noise at night from any place in that area of the ship. We have had a cabin on the Aloha deck and were very pleased. It was convenient to the buffet

Hope you enjoy your Princess cruise, they are our favorite line. We have not sailed on the Coral (yet), but have loved every ship we've sailed on. We have been on various decks and really not had any problems with noise. Best wishes!
