Pat, I just want to mention that while the norm is to have a formal night on an eight night cruise, there have been instances when this was not the case due to the itinerary. I believe in those cases there was not a sea day. So if you don't have a sea day you may want to write to on-board guest services a couple of months before the cruise to verify this. Their e-mail address is: obgs@crystalcruises.com
