The Dawn Princess is one of Princess' older and smaller ships. It is in the Sun class of ships.
All of the information is available on Princess' web site, www.princess.com
We have sailed the Dawn, and although a smaller and older ship, it is very clean. It does not offer all of the larger amenities as the Grand class ships, such as Movies under the Stars, but has a more intimate feel. I personally enjoy the smaller ships as the public spaces do not seem as crowded. We have also sailed on the Sun Princess which is a sister ship to the Dawn. I think you will enjoy your cruise.
