You may want to consider posting a "Roll Call: Ship/Date" so people on the same cruise can find you.
Carnival will leave a "Carnival Capers" in your cabin every night which you can use to plan your next day's activities. It's the thing I look forward to every night after dinner, the show, stop by the casino, and a late night drink or snack!
Some even take a highlighter along so they can plan the next day out!
Great to have you on board!
