Dawn vs Ruby vs Brilliace

I just returned from the Canada/NE cruise on the Brilliance of the Seas and was pleased with most everything about this cruise (except maybe the weather!) and have been even more happy with the Princess Ruby. I am considering a cruise to Bermuda on the Norwegian Dawn, and I'd like to hear some pros and cons about NCL, specifically the Dawn. Thanks.

I've also been on the Ruby and enjoyed it, and I also love RCI Radiance Class ships.

Dawn, not so much. In fact, it is a ship that I will never sail again. Not only her, but because of how much I disliked it, I will also never book her sister ship, Star. Service was awful, the ship was poorly maintained, and the nightly waits for a dinner table for 20-30 minutes. I chose a 7 night Dawn cruise over a 5 night Radiance Class cruise out of Tampa and in the end, wished I had actually paid more for the 5 night cruise.
