I haven't been on a ship for Easter but have been onboard for Thanksgiving. It seems that the celebration depends upon whether it is a sea day or port day. In our case, we'll be in Casablanca. Regent tends to serve very traditional American dishes on holidays, so I fully expect ham to be on the dinner menu. Had it been a sea day, they may have had a special buffet in atrium. It will be quite festive on the Mariner for Easter:-)
