I strongly prefer ships with excellent observation lounges, so Encore/Bliss/Joy are my first choices. On Encore/Bliss, DD can save a few $$ by booking a studio. The Jewel class ships (Jewel, Pearl, Jade, Gem) are a close second. I really like the aft facing great outdoors on those. I haven't yet sailed Sun/Sky but have both scheduled and expect them to be similar to the Jewel class. I don't like Epic, but that has nothing to do with the nice bathroom arrangement that is just too "different" for many. POA is a POS, but fine for seeing HI.
