Hi Mandy Lee, welcome to Cruise-Chat. My co-worker sailed on the NCL Dawn last year and hasn't stopped raving about her. He was ready to sail again as soon as he stepped on board. He enjoyed all the restaurants on board, enjoyed snorkeling, said the crew was fantastic, and that the ship was beautiful. We sailed on the NCL Sky in July, only one problem, the cruise was too short
I'm sure you'll find plenty of people your age, plenty of fun things to do, and enjoy yourself so much that you'll book another cruise! Best wishes and once again, welcome aboard!
