I went on the DCL in Jan on a eastern 7 night Cruise and am going in May on the western... I?m actually bummed that on the western you have less days at Sea. I saw those as the days to sleep in enjoy the pool and Relax. I wore pretty much every night to dinner a polo shirt and a pair of jeans except for Palo and the formal night. Not everyone every night was dressed up, jeans and a polo shirt were just fine. I enjoyed the cruise only wish that we were able to spend maybe 2 more hours at Castaway Key because Serenity Bay was awesome adults only quiet and beautiful.
