After doing the freestyle, I believe I prefer the traditional style. I like having the same waiter every evening which makes for better service. I also like getting to know the other table mates on the traditional.
The freestyle was nice as you are not rushed to go to dinner whether you are hungry or not. We opted to have other guests sit at our table and met some interesting people.
I definitely liked the smaller ship over the mega ships. The staff seemed more attentive to the passengers. You have more interaction with the other passengers as you see them time and again.
Lots of storage space but very noisy from the movement of chairs and tables from the deck above.
