We went on a 5 night cruise on the Carnival Destiny for our honeymoon. I am going to break my review into different points about different aspects of the ship. Hope this is helpful!
Spa:
I went to a "Manager's Special" spa session that included a massage and facial. It was alright, I have received much better sessions at my local spa. I did not like the products that they used for my facial. I do not believe they were as high of quality as they indicated they were. The massage was nice though.
