We have had both a Mini and a Full Suite on the Dawn. In addition to Suxie's comments about a Full Suite, you also receive an initial bar set up. If you receive liquors you don't drink , you may switch them for something you prefer.
In a full suite you can wait in your room until your departure time when disembarking instead of waiting in the public area.
In a full suite you may also order dinner in your cabin selecting foods from the main dining room menus.
Hope that helps. Enjoy.
