Free Style cruising is an interesting theory, and I'm sure some people will love it.
I guess I experienced free style ,to some extent,on the Seabourn Sun this spring.. we could show up our dining room table anytime we chose to during dining hours.
The difference was the dining room was large enough to seat all the passengers at one sitting. Therefore we still got "our" table, with "our" tablemates, and with no waiting. Now that I enjoyed!!
