I haven't sailed on the Dawn, but we were on the Sun in October and it was top notch. this was our 11th cruise, so we have a pretty good idea of what constitutes a great ship, and we would have no trouble recommending the Sun to anyone. The service was just as good as on more traditional ships, we enjoyed the freestyle concept, and our dinners were all delicious. We also particularly liked the ports ---- we went cave tubing in Belize, shopped in Grand Cayman, and enjoyed Carlos and Charlies in Cozumel. Anyway, I think you'd have a great time on the Sun.
