zbuddy,
We (me 43, DW 44, DD 16, DS 8) have sailed
DCL twice with a third scheduled for November and the Voyager-class ships twice, The Explorer last August and the Navigator in February. Have the Mariner probable for Feb '04 and the Voyager a definite in October '04 from NYC. I have a fairly detailed comparison between DCL and the Voyager-class RCCL ships on my web site. E-mail me and I can give you the address.
Both are very good. We did not experience the issues that nosebuddy describes on the Navigator. In fact, the lines were extremely manageable, even during President's day week. We thought the varierty of food was better than DCL, and much more availability outside of the formal dining rooms, especially on the Promenade. Everyone is different, I guess.
Also on my site are the Compass activity sheets from both cruises. They are a good source of info. I tend to agree with tezb, we enjoy a little more night activities for adults, including the casino and the art auctions, and no ship I have sailed on comes close to the options on those ships.
