Would you choose the Carnival Conquest, Rhapsody of the Seas, or the Grand Princess cruise ship? - princess cruise ships

I am planning a trip, and my options have been reduced three ships. I would like information about the activities there for young people. I would like information on activities and public services on boats. Please give us accounts of the cruise for their holidays past and / or information contained on these boats!
