Iv been on the Voyager twice and I thought WOW the first time I boarded, but have not been on in over a year. The dining room is the best one I have ever seen to me of any ship. I love the whole promenade thing and the cafe at night to go to.
The best Princess ship I did was Caribbean Princess and I was not as wow'd but it was nice, less children perhaps, but the children never bothered me on RCL as they are usually tucked away in camp.
A little older crowd on Princess, so this can be a good or bad thing depending on your age.
