Well, if we're talking "Personal Choice" ala Princess Cruise Lines, that is still restrictive.. recommended dress codes still apply.
If we're talking "FreeStyle" ala NCL.. well its more lenient, but "some form" of dress code still applies, even if it's just pants and shirts.
The only one I know of which has NO dress restrictions, suggested or implied, is Windjammer .. and they come right out with it.. Windjammer Barefoot Cruises (pretty descriptive).
We went on NCL with their "Freestyle Dining". At dinner, the waiters and waitresses were having a good time, talking and fooling around. Finally got our main entree. Then we waited 15 minutes for dessert but got up and left. And they have the nerve to charge us (I think around $10 a day) on our account. Also they advertise all the restaurants that we can dine at. What they don't say is that of these 10 restaurants, 5 charge a premium to dine there. I prefer the old way of crusing.
If you're referring to the "Personal Choice Dining" program on Princess Cruises by your subject line of "Personal Choice," I highly recommend that you cancel your booking with Princess and rebook with Norwegian Cruise Line.
Princess Cruises still has formal nights -- and formal attire is expected throughout the whole evening -- even with the new "Personal Choice Dining" program. The "Personal Choice Dining" program means that you can now choose between "Traditional Dining" (with formal first and second seating) in one dining room or "Anytime Dining" (which operates like a restaurant ashore) in another dining room on all ships that have two or more main dining rooms. All dining rooms, however, still require the prescribed attire.
have we all forgotten Costa where you can wear your bed sheet to dinner for the toga party!.. talk about casual! when I was on Costa everyone wore their sheets. the conservative ones with clothes underneath and the others not!!! When in Rome! It was fun!
