I have yet to sail on the Carnival Dream but there are a number of threads on the Carnival board and here is a link to some great pictures that Cruisemates Editor, Paul Motter, took on his recent Dream cruise.
We did the Carnival Dream on the Trans Atlantic crossing 27 Oct-12 Nov. Wonderful ship, wonderful cruise. We even ran into very rough seas with hurricane Ida and she handeled it superbly although we had a few very rocky days. Very nice ship! I don't think you will regret sailing her.
